Auction Galleries reselling works do not issue Certificates of Authenticity. COA's should best be sought from the original artist or their foundations, which often refrain from giving written authentication opinions. Accordingly, works are sold as ATTRIBUTED to the artist or maker named in the description. These attributions reflect an OPINION and are intended to provide collectors, researchers, and institutions the opportunity to study and further contextualize the material offered or establish a work’s art-historical significance.
