Kudos!!! Excellent work on the part of your team in your assessment of the “Brown painting”. I only wish I had discovered your organization prior to my mom’s passing last June.

My mother was indeed told at the time of her purchase in the early 1950’s that the painting was entitled “The Virgin Birth” or something very similar to that label. It would also make sense that the painting was stolen/looted from a location in Spain by Napoleon’s invading troops in the early 1800’s and taken to France. Very astute analysis.

Although it is not a painting by Murillo, I appreciate the clues as to who the painter might have been otherwise. That gives us a few more avenues to pursue in determining a proper valuation/appraisal.

I appreciate your time on the appraisal. Life truly is something of "speculation". I have received an offer of 50k on this painting, once I received "authentication". I "speculate" that I can do better.

Mark, thank you for spending the time!

With me for a client I bet you wish you had gone to Bora Bora! I appreciate the report it is so interesting. I had never done anything like this before, I don't have that kind of jewelry, so I was a bit worried about getting the appraisal. You have been more than great to work with, very patient with an old lady.

Wow. Awesome. Thank you so much for the information.

Thanks for the sharing a draft of the appraisal review for the referenced art piece. This is a very comprehensive and in-depth analysis of this work of art; It is a class lecture on itself. I am confident UPR and (re)insurers alike will find this study very useful, which has never been done for the University of Puerto Rico.

An exemplary project-I was presented with a comprehensive research and valuation on my Picasso - at a very fair price and within a very quick timescale.

I am pleased with the report. Thank you for the report it is very insightful.

Thank you for your reply and the positive comments your are giving me. Frankly, this is the first time that somebody gives me clear advices and steps to follow.

Thank you. Appreciate the expert review and quick response.

I asked so many people for help on this but no one's ever replied. I appreciate you taking the time.

You did an outstanding job! Thanks!!!!!!!

Sophie -that was a very helpful and a nice analysis. I thank you. I have some others to work with you and I will send you some outlines of what we would like you to consider. Thanks for a nice project.

Excellent analysis. Too bad, but I really appreciate your work and cannot help but agree with your conclusion.

About F. H. Brigden: I am sure you must get bombarded with questions and e-mails, phone calls similar to mine and I so appreciate you taking the time to share your expert knowledge. You DO know that you are the ONLY one out there I've been able to find on the net (or anywhere for that matter) not charging an arm and leg for their time / input, right? So thank you very much!

Thank you so much for all your hard work! Please extend my thanks to your team as well!

Thanks so much for at least listening to me-I will do what I have to-you are the only one to respond to me.

Thank You so very much for your very helpful report.

Thank you very much, Mark Winter.

Thank you very much. I appreciate the quick turn around time.

Thanks. You are doing a great job for me and I appreciate it.

Thank you for all your help and time on this matter. I will be laughing at this for a very long time. Thanks Mystery solved.

I deeply wanted to thank you for the reports. We were very impressed by the knowledgeable and scientifically prepared research. We would also like to thank you for the quick and uncomplicated transmission!

How can I thank you? You are so very nice to do this for me. I so wish that you were close and I could show you. Where are you located? I am in Houston, Texas. THANK YOU SO MUCH.

Thank you sir very much for your objective opinion with regards to the rape of Europa statue.

Thanks very much for the quick response!

I greatly appreciate your time!

Thank you very much for helping us settle this matter.

Ich möchte mich noch einmal für Ihren sehr kundenfreundlichen Service bedanken. Das ist heutzutage keineswegs selbstverständlich. Ich kann Sie nur bestens weiter empfehlen. Wünsche Ihnen alles Gute

The appraisal was great, can you be of any help in selling the Bronze. Thanks.

Several years ago I inherited, from my grandfather, a small anonymous painting from 1753. It had been among my family for the past 260 years, so it certainly had an emotional value besides whatever monetary value it could have. Considering the painting is anonymous we thought that it would be hard to trace, however we gave it to Art Certification Experts to research and the results where just phenomenal. In about one week I had an answer. They actually started the research in Spain and ended up informing me that the painting was most likely from Venezuela and that in fact it could have some relationship to Jose Antonio Paez the first president of Venezuela. This was a surprise to me because I had never told them I was from Venezuela and that I was a descendant of the first president. I was always told that the painting was from Spain so I never informed the Art Certification Experts of my origin. Now they are working to confirm if the painting is from a well known colonial artist or simply it came from one of the schools. This assures me that the word "Experts" is not just part of their name, they have proven it.

We're really very grateful to you for your research. It's hard to render our joy and enjoyment! Thank you.

Dear Art Certification Experts, On behalf of my mother, and our family, I wish to express our gratitude for your most kind assistance in this regard.

Thank you and your colleagues a lot for your appreciated work.

I wanted to thank you for the evaluation of the painting. Great analysis and detail on the provenance was interesting. Always learning about these different people in the business of art is in itself interesting. I look forward to connecting with you in the future.

It’s not everyday somebody successfully bursts my bubble, but you have done an excellent job of it. Nice to know my Baku has a sibling. Thanks.....

Thank you for the response. It was helpful.

Many many many thanks for your time, kindness and professionalism. Thanks much.

Thank you Mark, for your forthright observation. I appreciate your time and prompt response.

I think it fantastic what you are doing , and I admire your commitment and drive! Thanks for all of your hard work in solving the mystery.

Thanks for your reply. If you remeber you supported me with a portait od Mrs Siddons. Through anaylsis of the paint we could confirm that it was a 19th century copy. So the analysis done by your team was quite accurate.

We appreciate your objectivity. In fact, "balanced objectivity" is exactly what we need so that we know where we stand regarding the paintings.

Thank you for your time and attention to this. I sincerely appreciate it.

Thank you very much for the comprehensive letter of opinion. I think its perfect and will serve the intended purposes.

I just received your report mailed to my address. It is a document of good quality. I hope to have other opportunities to use your services.

Thank you for your email. I am really touched by your highly courteous, delicate and professional way in handling the subject and I am glad that there are still such a candid people in the world.

Wow This is amazing.... Thank You for this.... I Look forward to Seeing Man with Glass and the Bouquet.... As well. Thanks again for the efforts Thus far.

Thank you for the very thorough, professional report. I have to say that I suspected your conclusion. I would definitely recommend your service to other art buyers who are uncertain about their pieces.

Thank you kindly, You have been wonderful.

Thank you for your well done documentation.

I thank you very much for this interesting opinion. I am very grateful for it.

I appreciate your team's thorough analyses on the works. Fantastic job, excellent , very much professional, I'm sorry I was rushing you. What is next, how long carbon dating takes? We are very happy.

Thank you very much for your quick feedback as well as for your expertise on Theodore Rousseau. Thank you very much!

Thank you for your email. Bummer, I will send other pieces your way if I find that they need to be authenticated, or not as in this situation.

Thank you so much for your swift and kind reply, I really appreciate it! Best wishes from Sweden

Many thanks for your kind attention and time.

Excellent. Thank you very much. Quality services like yours is hard to find.

I did not expect a response on a Sunday but thank you for replying so promptly and so honestly.

Thank you so much. I guess my original "expert" was way off base. I really do appreciate your time and expertise.

Thank you very much for the information. I really appreciate your honesty and your time looking at these pieces.

TThank you so much for the response (and so quickly)!

I would say that you have Dr. Watson's deductive reasoning skills.

Thank you - so appreciate your assessment!

I appreciate your team's thorough analyses on the works.

What a wonderful report and informative information about Van Gogh! Wonderful Job on the review of the painting. Thank you so much!!! Worth the looking into.

Your explanation is very much appreciated. Thank you for all you do!

Thank you. Your expert opinion is greatly appreciated.

You guys are an awesome resource.

Thank you! Your assistance was greatly appreciated!

Thank you so much for your help. We settled the case based on your expert opinion that the pastel was a Renoir style. Not a genuine Renoir. The dealer returned the purchase price, paid my attorney, and court costs and the case was closed.

Thank you for the work you have done with the drawing.

I appreciate it. You don't find such kind people often.

Thank you for your honesty.

The thing is your credentials are extraordinary

Thank you for the prompt and very thorough authentication of my lithograph. I’m glad to hear it’s good to go.

Thank you very much for your comments and professional assessment of both the ballerina and the Hiroshige pictures. I appreciate your site and your help.

Really Thank you for your fast answer.

Hello Mark, many thanks for your email and attachments, I hope all is well, I will follow your help and advice and forward the results to yourself as soon as possible. I greatly appreciate your guidance, I am unsure of any fees involved and will be very happy too discuss them further, thank you for helping me along with this learning curve. I'm very grateful and enjoying your help very much. I will forward my results very soon.

Well, I opened the back and took it apart, and it is just a print. I appreciate your patient and kind responses to me.

Thanks for the super fast service. Great day to you.

Many thanks for the clear and unambiguous reply.

Thank you. Saved me lots of hours of research.

Thanks so much for the advice. Very much appreciated.

Thank you Mark. I appreciate your assistance.

Thank you Mark. I really appreciate the quick turn around and envy your Art knowledge.

Thank you very much. Your point by point analysis is really what I needed, especially after going through scads of "Expert" opinions that seem to rely more on gut feelings than the actual work itself.

A big thank you for the updated and report. Hope you had a great summer!

Thank you so much for your information. You are the first person who has answered my questions, seemed to have any knowledge of what needed to be done, and hasn't just brushed me off because of my last name and the fact that I live in Texas. No one had taken me seriously, and I guess that will be their loss.

You've been very helpful. (I can't read Japanese so I had no idea what it said on the back).

Love your honesty!!!

That might be the fastest reply I’ve ever received thank you Mark that was incredibly generous of you.

Thank you so much for the time you took to help me out, I appreciate it so much.

Thank you for the thoughtful and careful analysis of the painting. Your conclusions are well argued and persuasive. I, for one, am convinced.

Understood, thank you for your time and expertise.

Thank you very much for your preliminary opinion on the painting. I am happy to put further questions and research to rest.

TMy sincere thanks to you for your review, and especially for your expertise! I'll now have an accurate understanding of it's origins in the era in which it was crafted. That alone adds intrinsic "value" to this set as an heirloom and a part of our family heritage. It's heartening to know that there remain those experts like you who recognize and appreciate those antiques and items of historical significance. We salute you, sir!

Thank you so much for taking the time to thoughtfully address my concerns about the bronzes. I can't tell you how much I appreciate your efforts.

Thanks a lot for your rapid reply. I was also doubting about this signature, and I'm glad that I did not purchase the painting for even small money.

Vi ringrazio per la collaborazione. Grazie mille !!

Grazie per il lavoro eseguito. Il Vostro compito e stato compiuto con una altissima professionalita.Complimenti e grazie.Con stima.

Thanks!! You save me $$$$

Thank you very much for this investigation....happy to get it behind us! I will certainly recommend you in the future.

Thank you kindly, You have been wonderful.

Although the painting isn’t by the artist I thought it was your evaluation is amazing and well worth the money I paid for service and like Chris rock said after getting slapped by Will Smith at the Oscars, Wow!

You are awesome! I can't thank you enough for your help.

Once again it was a pleasure doing business with Art Certification Experts.

So nice of you to take the time with me. Thank you. And impressive you know this and can only imagine what you all know.

Boy, that was easy. Thanks

Thank you for your extremely thorough analysis.

Thank you for your diligent work. It's remarkable that you found a work that also shows a man in a poncho sitting across from a llama.

The work product you provided is outstanding.

Thank you for your great work on the von Bremen. The Final Report came today we are thrilled. I am sending your way images for the possible Pierre Lacour. Others to follow after this e-mail. Do you think this oil on board is worthy of possible authentication. Thank you for your expert eye.

Thank you for your thorough report and speedy turn around on this project. I will certainly use ACE in the future.

Thank you so much. You’re amazing.

Excellent report! I cannot praise it enough. Congratulations to your team for providing such an exquisite example of critical thinking.

Awesome, thank you so much!

Your explanation is very much appreciated. Thank you for all you do!

It is such a relief to know that there is someone like you and your staff out there that provide art expert advice and research at reasonable rates with such integrity, expertise, and professionalism, including returning calls and emails in a timely fashion. I no longer feel professionally isolated in my attempt to find out what, if anything, my paintings are worth.

Thank you for this – exactly what I hoped to receive. I will have one more for you shortly if that is okay.

Outstanding call, thank you Sir.

You were so much more helpful and accommodating than anyone else I had corresponded with. Thanks again.

You are awesome! I can't thank you enough for your help.

Thank you so much for your expert opinion Mr. Winter.

Sorry it has taken so long to get back to you. I wanted to say thank you for the effort forwarded to my little statue. I had no idea anyone would go to so much trouble for something so small! I hope that in the future, I will have something worthy of a formal appraisal. Thank you.

Thank you so much, your estimate on this painting seems pretty reasonable to me and is a good bit more than I paid, thank you very much for your efforts. Its certainly nice to know I didnt blow money on a bad purchase. Thanks again and in the future I wouldnt hesitate to use/recommend your services.

Thank you! Very thorough.

Thank you very much for your assistance.
