Artwork Authenticity and Certificates of Authenticity

A guarantee of authenticity for every artwork sold

Every artwork sold through our website or purchased in person at one of our two Paris galleries, Le Coin des Arts, is guaranteed authentic and accompanied by its certificate of authenticity.

This document is a key element of provenance and security for collectors, certifying the origin, authorship, and exact nature of the artwork.

Issuance and delivery of the certificate of authenticity

The certificate of authenticity is provided at the time of purchase or, when applicable, sent by mail at a later date.
For online purchases or shipment requests, the certificate is included directly in the package containing the artwork, placed in a separate protective cardboard envelope to ensure proper preservation.

Posters and unsigned prints

For posters and unsigned prints, no certificate of authenticity is issued by default.
A certificate may nevertheless be issued upon the client’s explicit request.

Issuance of certificates and expertise

Certificates of authenticity are issued by Galerie Le Coin des Arts and signed by Thaddée Poliakoff, a member of the CSEDT (Chambre Syndicale de l’Estampe, du Dessin et du Tableau), the SLAM (Syndicat national de la Librairie Ancienne et Moderne), and the CNE (Compagnie Nationale des Experts).

Thaddée Poliakoff is an expert in modern and contemporary prints.
He is also a recognized expert on the work of Serge Poliakoff, his grandfather, and director of the Serge Poliakoff Archives.

A unique, original, and named certificate

We never provide copies of certificates, whether as photocopies sent by mail or as PDF files by email.
Only one original certificate is issued per artwork and is delivered exclusively to the purchaser.

This strict policy ensures the uniqueness of the document and helps prevent any fraudulent use.

Unique artworks and certificates issued by committees or estates

In the case of a unique artwork (drawing, gouache, or painting), we work, when required, with the appropriate expert, committee, or estate to provide the collector with a certificate issued directly by the entity responsible for the artist’s catalogue raisonné.
