COULD YOUR PAINTING BE BY ALBERT GUILLAUME?

Previously unknown works by important artists continue to emerge from private collections, estates, inheritances, and long-held family possessions. While authentic paintings and drawings by Albert Guillaume 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 Albert Guillaume, obtaining an independent professional opinion is the appropriate first step.

We have specialized in the authentication of works attributed to Albert Guillaume 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.

Albert Guillaume is documented as a painter, aquarellist, draughtsman and illustrator, with paintings, watercolors, drawings, illustrations and poster work all relevant to his artistic output.

AUTHENTICATION

Is this an Albert Guillaume?

From photographs of ordinary quality, we can often determine whether a work appears consistent with Albert Guillaume's known production or whether it clearly does not. Because his output includes both fine-art painting and highly circulated illustration and poster material, attribution should be considered in relation to the specific medium, subject and period.

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 Albert Guillaume today?

Yes. Paintings, drawings and illustrated works can remain in private collections or family holdings for decades without being properly identified, making professional examination worthwhile when the attribution is plausible.

Do I need to get my Albert Guillaume 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 an Albert Guillaume authenticated?

Not for you. Simply send us photographs of the front and reverse, close-ups of the signature and other important details, the dimensions, and anything you know about the work's history. The investigation itself is our responsibility.

How long does it take to authenticate an Albert Guillaume?

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 an Albert Guillaume?

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 an Albert Guillaume painting is authentic?

No. A signature can provide useful evidence, but it must be evaluated alongside the painting's materials, technique, composition, date, condition and documented history.

Can an unsigned Albert Guillaume painting still be authentic?

Yes. The absence of a signature does not by itself exclude an authentic painting, and attribution should be based on the complete body of evidence rather than the presence or absence of a name.

What documents help authenticate an Albert Guillaume painting?

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 an Albert Guillaume painting be authenticated from photographs?

Yes. High-quality photography is an extremely useful authentication tool and allows us to study 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 an Albert Guillaume painting?

No. Many works can be authenticated through research, provenance investigation, stylistic and technical analysis, and examination of the physical evidence. Scientific testing is generally reserved for more difficult cases when questions remain concerning the age or composition of materials.

What if my Albert Guillaume 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 Albert Guillaume works?

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

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 Albert Guillaume 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 an Albert Guillaume?

Higher-value paintings 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.
