Artworks by Hans Arp and Sophie Taeuber Arp can be registered at the Stiftung Arp e.V.. All works will be examined beforehand for their authenticity. During the authentication process, external experts and colleagues from the Fondazione Marguerite Arp-Hagenbach in Locarno and the Fondation Arp in Clamart may be consulted on a case-by-case basis. The purpose of this endeavor is to establish the most comprehensive documentation of Hans Arp and Sophie Taeuber-Arp’s oeuvres for the Stiftung Arp e.V. archive. We are under no obligation to document works.
The Stiftung Arp e.V. welcomes questions regarding works by Hans Arp and Sophie Taeuber-Arp’s art as well as works attributed to the artists. During the authentication process, a committee of experts and colleagues from the French and Swiss Arp Foundations are consulted. The foundation does not give price estimates or make appraisals. Every year 1-2 dates for exptertises are offered. For this expertise the original works have to be send to the Foundation. A service charge applies to the examination of works. To have your work authenticated, please contact us directly.
