COULD YOUR ARTWORK BE BY GUIDO RENI?

Previously unknown works by important artists continue to emerge from private collections, estates, inheritances, and long-held family possessions. While authentic works by Guido Reni may be rare, every work deserves to be evaluated on its own merits rather than dismissed simply because it is unfamiliar or undocumented.

If you believe your painting or drawing may be by Guido Reni, obtaining an independent professional opinion is the appropriate first step.

We have specialized in the authentication of works attributed to Guido Reni since 2002. We issue Certificates of Authenticity (COAs), Authentication Reports, appraisals, valuations, provenance reports, and provide buying, selling, brokerage, and investment advisory services for collectors, attorneys, insurers, financial institutions, estates, museums, and private clients worldwide.

Getting started is straightforward. Simply send us photographs of the work together with its dimensions and any information you have regarding its history or ownership. After reviewing the material, we will recommend the most appropriate course of action.

AUTHENTICATION

Is this a Guido Reni?

From a single photograph of ordinary quality, we can often determine whether a work appears consistent with Reni’s work or whether it clearly does not. His paintings vary in scale, finish, subject, and period, and works produced by his workshop and followers can make attribution more complex.

What services do you provide?

We provide authentication, certification, Certificates of Authenticity (COAs), Authentication Reports, appraisals and valuations, provenance research, private sales and brokerage, investment advice, and analytical art market research.

Is it possible to discover a previously unknown Guido Reni today?

Yes. Reni maintained a highly productive workshop and produced paintings and drawings during a long career, so undocumented works can still emerge from private collections, estates, and long-held family possessions.

Do I need to get my Guido Reni authenticated?

Yes. Authentication is essential if you wish to sell your work for its full market value. It is also important for insurance, estate planning, charitable donations, financing, and many legal purposes.

Is it complicated to get a Guido Reni authenticated?

Not for you. Simply send us photographs of the front and reverse, close-up photographs of important details, signatures or inscriptions, the dimensions, and anything you know about the work’s history. The investigation itself is our responsibility.

How long does it take to authenticate a Guido Reni?

It depends on how much is already known about the work when we begin the investigation. In the simplest cases, authenticity can be confirmed within a couple of weeks. More complex cases may require several months.

How much does it cost to authenticate a Guido Reni?

From the low hundreds to the high thousands. It depends on how much is already known and documented, where relevant archives are located, and whether travel or scientific testing is required.

Can a signature alone prove that a Guido Reni painting is authentic?

No. A signature or inscription must be evaluated together with the painting’s materials, technique, support, surface, provenance, proposed date, and other physical and documentary evidence.

Can an unsigned Guido Reni painting still be authentic?

Yes. The absence of a signature does not by itself make a painting attributed to Reni inauthentic. Authentication depends on the totality of the physical, technical, stylistic, and documentary evidence.

What documents help authenticate a Guido Reni painting or drawing?

Any document that mentions, describes, illustrates, or refers to the work may assist the authentication. Photographs, invoices, correspondence, exhibition records, restoration or conservation reports, insurance documents, auction records, and family papers can all contribute valuable evidence.

Can a Guido Reni painting or drawing be authenticated from photographs?

Yes. High-quality photography is an extremely useful authentication tool and allows us to study composition, paint application, drawing technique, support, surface, inscriptions, and other important characteristics remotely. When additional evidence is required, we may recommend an in-person examination. We examine works worldwide.

Is it always necessary to perform scientific analyses of a Guido Reni?

No. Many works can be authenticated through research, provenance investigation, analysis, and technical examination. Scientific testing is generally reserved for more difficult cases when questions remain concerning the age or composition of pigments, grounds, canvas, panels, paper, inks, or other materials.

What if my Guido Reni has no provenance?

Incomplete provenance is common. When provenance is incomplete, authentication relies more heavily on research, technical examination, photography, and, where appropriate, scientific testing.

Do you issue Certificates of Authenticity for Guido Reni works?

Yes. Upon completion of the authentication, we issue a Certificate of Authenticity (COA) together with a detailed and fully referenced Authentication Report.

APPRAISALS & VALUATIONS

How much is my Guido Reni painting or drawing worth?

We will appraise your work and determine its value. Medium, date, subject, dimensions, condition, provenance, quality, rarity, and market demand are among the principal factors that may affect value.

SELLING

Can you sell my Guido Reni for me?

Yes. We specialize in private sales but use every appropriate selling method to obtain the highest possible net price. We manage the process professionally, confidentially, and on your behalf.

Do I need an appraisal before selling my Guido Reni?

Yes. Your work should be priced correctly for the country, market, and method of sale. An independent appraisal helps prevent both underpricing and overpricing.

Do I need authentication before selling my Guido Reni?

Yes. Without authentication, your work may sell for only a fraction of its potential market value.

Can you help me maximize the selling price of my Guido Reni?

Yes. Authentication, provenance, valuation, timing, presentation, and the chosen sales method can all influence the final result. We also provide collection management advice designed to maximize value.

Should I restore my Guido Reni before selling it?

Usually not. Buyers often have their own preferences regarding conservation and restoration. We generally recommend selling the work in its present condition unless there is a compelling reason to do otherwise.

How long does it take to sell a Guido Reni?

Higher-value works generally require more time to sell because there are fewer qualified buyers. Correct pricing, strong documentation, and the appropriate sales method all contribute to a successful sale.

BUYING & ADVISORY

Should I buy a Guido Reni?

If you enjoy Reni’s work, certainly. If your primary objective is investment, we can evaluate the proposed acquisition and alternative opportunities.

Can you review a Guido Reni before I buy it?

Yes. We provide independent pre-purchase research and analysis for collectors and investors. We also prepare predictive art market forecasts and Buy-Hold-Sell recommendations.

What should I check before buying a Guido Reni?

Three fundamental questions should always be answered: Is it authentic? What is its condition? Is the price reasonable? For works attributed to Reni, careful distinction between autograph paintings, workshop production, copies, and later imitations can be particularly important.

How can I avoid buying a fake Guido Reni?

Call us before you buy. An independent review before completing the purchase is one of the simplest ways to reduce the risk of acquiring a forged or misattributed work.

Can you advise me on building a collection?

Yes. We advise collectors on the financial aspects of acquisition, ownership, collection management, and eventual sale.
