The Department

The Modern and Contemporary Art Department is best characterized by its dynamic growth. The art historian Robert van den Valentyn leads a competent and international team of experts who specialize in painting, sculpture, and graphics. They gladly provide personal and individualized consultation. Their combination of extensive market knowledge and experience ensures that you will receive the highest possible returns.

Whether modern artists such as Emil Nolde, Willi Baumeister, Alexej Jawlensky and Rudolf Bauer or contemporary creators like Sigmar Polke, Gerhard Richter and Andy Warhol: VAN HAM's close contacts with a global network of major collectors ensures the optimal conditions for a profitable sale. The department engages particularly with works created by key artist-members of the ZERO Group: among them, Günther Uecker, Otto Piene, Heinz Mack, Yves Klein, Gotthard Graubner and Lucio Fontana. Numerous works have been sold into museums and international collections.

Through intensive and personal exchanges with museums, foundations, and private collections, we guarantee an exclusive group of bidders. We regularly achieve international record prices and would be pleased to advise you on the best means of marketing your art.
