We use the well-respected and recognized techniques of Morellian and van Dantzig analysis to look for inconsistencies that may include, but are not limited to:

• the artist’s signature

• color choices

• brushstroke patterns

• anatomy and facial features

• landscape details

• architectural details

• costume details

• dimensions

We also consider the composition as a whole and how it fits into the artist’s personal and professional timeline. In most cases, if at least three major inconsistencies are found, we conclude that the artwork in question is not authentic.

When possible, we use the artist’s catalogue raisonné as a source for comparable works of art. If an artist does not have a catalogue raisonné, we may also rely on museum collections, exhibition catalogues and records of sale from major international auction houses.

Our pricing for this service varies based on the complexity of research required. Submit your artwork for a free assessment using the “check eligibility” button above and we’ll respond with a personalized estimate within 48 hours.

The deliverable for comparative analysis is an illustrated report of at least 20 pages, which documents research methods and findings to support our authenticity conclusion. It includes a full bibliography and may contain recommendations for further research.

Standard turnaround time is two to four weeks, but may vary based on our current volume and the complexity of research required to authenticate your work of art. Rush delivery is available upon request.
