Drouot Digital
The Company

Expertissim is the leading Internet platform specialized in the sale and purchase of works of art and antiques authenticated by recognized independent experts.

With the support of over 40 of the most highly esteemed independent experts in the market, Expertissim has rapidly established itself as both a trusted third party and the leader in this market segment.
