COULD YOUR PAINTING BE BY LUDOLF DE JONGH?

Previously unknown works by important artists continue to emerge from private collections, estates, inheritances, and long-held family possessions. While authentic works by Ludolf de Jongh 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 may be by Ludolf de Jongh, obtaining an independent professional opinion is the appropriate first step.

We have specialized in the authentication of works attributed to Ludolf de Jongh 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 painting 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 Ludolf de Jongh painting?

From a single photograph of ordinary quality, we can often determine whether a painting appears consistent with de Jongh’s work or whether it clearly does not. His known production includes genre interiors, portraits, hunting scenes, and other figure compositions, and some works have historically presented attribution problems with other Dutch painters.

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 Ludolf de Jongh today?

Yes. Seventeenth-century Dutch paintings can remain in private collections for generations under old, uncertain, or lost attributions. De Jongh’s works have also been confused with those of other painters, making careful reassessment worthwhile.

Do I need to get my Ludolf de Jongh 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 Ludolf de Jongh authenticated?

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

How long does it take to authenticate a Ludolf de Jongh?

It depends on how much is already known about the painting 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 Ludolf de Jongh?

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 Ludolf de Jongh painting is authentic?

No. Signed examples are known, but a signature must be evaluated together with the painting’s technique, materials, composition, age, and provenance. One documented painting, for example, bears an indistinct “L D Jongh” signature.

Can an unsigned Ludolf de Jongh painting still be authentic?

Yes. An unsigned painting can still merit serious investigation; a National Gallery interior tentatively attributed to de Jongh is unsigned and has historically been associated with numerous different artists.

What documents help authenticate a Ludolf de Jongh painting?

Any document that mentions, describes, illustrates, or refers to the painting 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 Ludolf de Jongh painting be authenticated from photographs?

Yes. High-quality photography is an extremely useful authentication tool and allows us to study composition, figure types, interiors, paint handling, signatures, inscriptions, surface characteristics, and condition 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 Ludolf de Jongh?

No. Many paintings can be authenticated through research, provenance investigation, comparative analysis, and technical examination. Scientific testing is generally reserved for more difficult cases when questions remain concerning the age or composition of the support, ground, pigments, or other materials.

What if my Ludolf de Jongh 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 Ludolf de Jongh 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 Ludolf de Jongh painting worth?

We will appraise your painting and determine its value. Important factors include subject, period, dimensions, support, condition, provenance, quality, rarity, attribution certainty, and current market demand.

SELLING

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 Ludolf de Jongh?

Yes. Your painting 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 Ludolf de Jongh?

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

Can you help me maximize the selling price of my Ludolf de Jongh?

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 Ludolf de Jongh before selling it?

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

How long does it take to sell a Ludolf de Jongh?

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.

What should I check before buying a Ludolf de Jongh?

Three fundamental questions should always be answered: Is it authentic? What is its condition? Is the price reasonable? Attribution deserves particular attention because paintings associated with de Jongh can overlap stylistically with works by other seventeenth-century Dutch genre painters.

How can I avoid buying a fake Ludolf de Jongh?

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 painting.
