COULD YOUR ARTWORK BE BY GUSTAVE CAILLEBOTTE?

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

We have specialized in the authentication of works attributed to Gustave Caillebotte 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 Gustave Caillebotte?

From a single photograph of ordinary quality, we can often determine whether a work appears consistent with Gustave Caillebotte’s work or whether it clearly does not. A first impression may not be definitive because his subjects and compositions range from ambitious scenes of modern Paris and domestic interiors to portraits, landscapes, gardens, boating subjects, still lifes, drawings, and pastels.

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 Gustave Caillebotte today?

Yes. Caillebotte produced a considerable body of paintings, drawings, and pastels, and previously undocumented works can still emerge from private collections, estates, inheritances, and long-held family possessions.

Do I need to get my Gustave Caillebotte 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 Gustave Caillebotte authenticated?

Not for you. Simply send us photographs of the front and reverse, close-ups of the paint or paper surface, support, signature, inscriptions, labels, stamps, framing information, and other important details, together with 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 Gustave Caillebotte?

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 Gustave Caillebotte?

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 Gustave Caillebotte painting is authentic?

No. A signature must be evaluated together with technique, materials, support, date, provenance, inscriptions, labels, and documentary evidence. Signatures can be copied or added later and should never be considered independently of the work itself.

Can an unsigned Gustave Caillebotte painting still be authentic?

Yes. The absence of a signature does not by itself establish that a painting is inauthentic. Attribution must consider technique, materials, provenance, date, documentary evidence, and comparison with securely documented works.

What documents help authenticate a Gustave Caillebotte painting?

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

Can a Gustave Caillebotte painting be authenticated from photographs?

Yes. High-quality photography is an extremely useful authentication tool and allows us to study composition, paint surface, support, signature, inscriptions, labels, stamps, 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 Gustave Caillebotte?

No. Many works can initially be assessed through research, provenance investigation, comparative analysis, and technical examination. Scientific testing may be appropriate when questions remain concerning pigments, binders, canvas, grounds, paper, pastels, or other materials.

What if my Gustave Caillebotte has no provenance?

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

Do you issue Certificates of Authenticity for Gustave Caillebotte 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

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.

Yes. Authentication, provenance, valuation, condition, scholarly documentation, 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 Gustave Caillebotte 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.

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.

How can I avoid buying a fake Gustave Caillebotte?

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