In his works, Imi Knoebel (born 1940 in Dessau) draws in the widest possible sense on the abstract art found in classic modernism. He creates as yet non-existent levels of reality, reduced to the specific, basic elements of artistic work. In 2011, Imi Knoebel designed the windows in the Royal Cathedral in Reims. The focal point of the exhibition is the monochrome-white, pictorial object "Mennigebild 17/33" dated 1976/2007 from Dieter and Si Rosenkranz's collection. Three large-format, abstract works and one room installation are also on show as references.
