Frequently Asked Questions

While reaching a final conclusion requires exhaustive research, examining detailed photography allows us to evaluate whether physical traits match VINCENT VAN GOGH's recognized body of work or indicate clear anomalies. Van Gogh's intense decade of output traversed distinct creative eras—from his early Dutch period in Nuenen to Paris, Arles, Saint-Rémy, and Auvers-sur-Oise—each characterized by specific handling of technique, brushwork topography, color palette, and signing habits.

We offer official authentication assessments, Certificates of Authenticity (COAs), comprehensive physical reports, appraisal and market valuation documentation, provenance reconstruction, private sales representation, and strategic art market advisory.

Yes. Although Van Gogh's primary painted works are heavily documented, early drawings, works on paper, gifted studies, sketches within letters, and pieces given to contemporary peers continue to emerge worldwide.

Establishing clear verification is essential to achieve full value upon sale and is required for securing insurance policies, settling estate matters, collateralized financing, and processing tax-deductible gifts.

The process is straightforward on your end. You only need to provide high-resolution images showing the overall piece, reverse side, signatures (if present), canvas weave, and close-up impasto details, along with measurements and known ownership history. Our team coordinates all research and technical analysis.

Turnaround times vary based on the extent of preexisting documentation. Straightforward cases can be resolved within a few weeks, whereas complex inquiries requiring archive access, catalogue raisonné alignment, or laboratory testing may take several months.

Fees range from the low hundreds to several thousand dollars, depending on the volume of archival research required, location of records, and whether scientific material testing is necessary.

No. Van Gogh signed only a fraction of his completed works—typically signing simply "Vincent" when he considered a canvas finished—and period-appropriate fakes or later added signatures are common.

Yes. The majority of Van Gogh's paintings, drawings, and working studies were left unsigned at the time of his death and remained in the care of his family.

Any archival documentation referencing the piece—such as vintage gallery receipts, historical invoices, early exhibition logs, period photographs, family correspondence, estate inventories, or conservation records—provides crucial supporting evidence.

Yes. Advanced digital photography enables our specialists to examine critical physical features remotely, including paint application density and brush topography. If photographic evidence proves inconclusive, we can arrange an in-person physical inspection anywhere in the world.

No. A significant majority of works are verified through stylistic comparison, archival research, and technical material examination. Scientific testing (such as pigment analysis or canvas weave analysis) is used primarily when questions remain regarding material age or chemical composition.

Incomplete provenance is common for late 19th-century works. When historical paper trails are missing, authentication leans more heavily on technical study, material analysis, comparative stylistic review, and targeted research.

Yes. Upon successful verification of authenticity, we issue a formal Certificate of Authenticity (COA) accompanied by a fully referenced report detailing our findings.

We conduct professional market valuations to calculate precise appraisal values. Primary valuation drivers include the artistic period (with Arles and Saint-Rémy works commanding top-tier market interest), medium, rarity, subject matter, condition, color preservation, and historical provenance.

Yes. We represent owners through confidential private sales and targeted placement strategies to maximize net financial return while protecting client privacy.

Establishing an accurate valuation ensures your artwork is priced correctly for current market conditions, avoiding both financial under-monetization and long-term market stagnation.

Yes. Unverified works sell at a significant discount; verified documentation and authentication are necessary to achieve full fair market value.

We optimize real net returns through proper physical presentation, authenticated documentation, targeted marketing to established collectors, and selecting the optimal sales channel.

Generally, no. Prospective buyers often prefer to oversee conservation decisions independently. We usually advise offering the piece in its current state unless structural conservation is urgently required.

Blue-chip Impressionist and Post-Impressionist assets typically require longer placement windows to connect with qualified purchasers. Accurate pricing, verified provenance, and clear authentication help streamline the sale timeline.

If your primary motivation is aesthetic enjoyment, yes. If your focus is financial growth, we supply comparative market analysis and risk assessments to evaluate acquisition opportunities.

Yes. We perform independent due diligence, physical condition assessments, valuation checks, and strategic Buy-Hold-Sell recommendations before transactions are finalized.

Three core factors must always be verified: authenticity, structural condition/integrity (including canvas relining and varnish state), and fair market pricing relative to recent sales comparisons.

Retain an independent specialist to evaluate the artwork, verify documentation, and conduct provenance checks before releasing funds or signing purchase contracts.

Yes. We advise private collectors, family offices, and institutions on acquisition strategy, long-term portfolio management, valuation updates, and liquidation options.
