Research Centre

This research institute focuses on the study of the life of Marc Chagall (1887-1985), his graphic work and stained glass windows. The research is made possible by the Wuyt Collection, which consists of a large library, many documents and thousands of original graphics.


You can go to the Research Centre for detailed information about a certain litho, etching, woodcut, heliogravure or pochoir. The Research Centre pays great attention to the authenticity problems with Chagall lithographs, etchings and woodcuts. Most of the forgeries in Chagall's oeuvre relate to works in these graphic techniques.


The Authenticity Certificates of the Research Centre (written in English) are world renowned and second to none. The thousands of certificates issued are one of the  pillars of our company. 


In the last twenty years the Research Centre was responsable for four hundred performances. 


Authentication Investigations

Detailed information about a litho, etching or woodcut. If you want to know more about a particular lithograph, etching or woodcut from Chagall, you can request it from us by email or in writing. Usually this is information that is not accessible along normal roads. For such specific questions we charge € 100. You will receive the result of our investigation by email or by post.


Certificates of Authenticity

We specialize in providing Certificates of Authenticity. A statement of authenticity assures both the buyer and the artist (in our case Marc Chagall and sometimes Charles Sorlier) of the authenticity of a work of art. Chagall was always deeply involved in the publishing of his graphic work, he was involved in printing, book production, circulation and, where appropriate, numbering and signing. Together with the year of issue and the title of the work, this information forms the basis of our Certificate of Authenticity.

The heart of the Research Centre lies in the study of Chagall's life and his graphic work. In thirty years this has led to five hundred readings, lectures, introductions and workshops throughout the Netherlands and occasionally outside these borders. Fifty publications appeared in Dutch. We intend to regularly (the framework of) place such a publication on the website under the title: PAPER OF THE MONTH. Click here for the list of papers.
