Christie’s presents the sale of three works by Carl Andre, Sol LeWitt, and Dan Flavin from the collection of Paul Maenz to be sold in the evening sale of Post-War and Contemporary Art on November 10th. Through his gallery and the artists he represented, Paul Maenz had a profound impact on Cologne’s importance as a cultural and artistic center. Specialized in works by conceptual artists early on, the Galerie Paul Maenz Köln was instrumental in introducing avant-garde art of the 1970s and 1980s to Europe. New York and Cologne have had a decisive influence on the art world, both cities afford the kind of climate that artists value and possess intuitions that both challenge and support the art scene.
