Authentications & Certificats

The costs of the expertise are free of charge.

In order to proceed with the expertise, we need the following elements by email to the following address: sergepoliakoff@free.fr

  • A high resolution picture of the work (jpeg)

  • A picture of the back of the work - in the case of a gouache, the work must be unframed - (jpeg)

  • A photo of the signature enlarged (jpeg)

  • The dimensions of the work (in centimetres)

  • As well as much informations as possible about the work (date, origin, history).

If the work is already listed in our archives, we can confirm its authenticity.

If the work is unknown to us, we will need to see the work at :

Le Coin des Arts Gallery,
6 rue de l'Echaudé 75006 Paris,

Or at Pixi Gallery (La Galerie Pixi),
