The segment of the big names

Modern painting, from 1860 to 1945, accounts for €9.3 billion in 2024: it is the largest share of the painting segment. The median price is €12,700 and the index rises by 5.4%.
It covers late impressionism, post-impressionism, fauvism, cubism, expressionism, abstraction and surrealism. Its artists are among the most famous on the world market.
This fame has a downside: modern painting is the segment most exposed to fakes.

Why fakes are numerous there
The value of signatures, the relative ease of imitating certain styles and the multiplicity of works on paper create fertile ground for fakes. Artists produced dozens of variants of the same subject, which makes distinction difficult.
Experts rely on catalogues raisonnés, the artist's archives, pigment analysis, which makes it possible to identify anachronisms, and study of the support and the frame. A pigment invented after the artist's death is enough to disqualify a work.



Artist committees and catalogues
For modern painting, the opinion of the artist's committee, often made up of rights holders, is an important element. These committees sometimes hold positions that diverge from those of independent experts, which can create deadlocks.
In that case, OIMAP's opinion is reasoned in writing, with the evidence that supports it. It can be set against the committee's before the Arbitral Tribunal. This procedure has been used in twelve cases since 2019.
Provenance and studios
A modern painting whose provenance goes back to the artist's studio, a famous gallery or a major collector benefits from a premium. Gallery archives, account books, studio photographs and correspondence are valuable sources.
OIMAP digitises gallery archives and makes them available to accredited experts. This documentary base has made it possible to dispel doubt in 340 cases since 2020.
