The market's go-betweens

Contemporary art galleries play three roles: they discover and support artists, they produce and distribute their works, and they sell. The primary market rests almost entirely on them.
There are 3,450 galleries and dealers registered with OIMAP, of which 1,380 have obtained the conformity label. They sell directly, at fairs and increasingly online.
This page describes how a gallery works, the relationship with the artist and the guarantees a gallery owner must offer clients.

A relationship of trust with the artist
A gallery represents an artist, often exclusively, in a geographic area. It organises their exhibitions, publishes their catalogues, negotiates their prices and, above all, protects their market value. A work sold too cheaply or a poorly managed auction resale can lastingly damage a career.
In return, the artist usually receives half of the sale price, excluding taxes. The contract specifies the duration, the exclusivity, the sharing of production costs and the fate of unsold works.



What a gallery must offer its clients
A serious gallery gives the buyer a signed certificate of authenticity, describing the work, the technique, the dimensions, the edition, the date and the provenance. It answers questions about the artist, the conservation of the work and the installation conditions.
It also commits to traceability: it declares its sales to the Observatory, informs the buyer of their rights and shows them how to have the work registered. The OIMAP conformity label attests that the gallery respects these commitments.
Galleries and the digital market
Galleries have embraced digital tools: online viewing rooms, online sales, digital certificates. This development has widened their clientele, but it demands new vigilance: identity checks, data protection, authenticity of images.
Labelled galleries can offer their clients digital certification of the work, which links the paper certificate to an online-verifiable record.
