We offer expert opinions on works by Rupprecht Geiger and Willi Geiger for museums, private collections, galleries and auction houses.
Proof of the authenticity of a work is only provided by the Geiger Archive if the work can be clearly traced in the archives of the artist Rupprecht Geiger.
For this purpose, it is not necessary to deliver the originals to us; we will gladly visit you at your premises.
