Besides important key works such as Raum 19 III (1968/2006), Batterie (2005), and the 21-part complex of works from the so-called Core Pieces, this catalog presents new works of art created by the artist Imi Knoebel (*1940) especially for the exhibition Guten Morgen, weisses Kätzchen (Good morning, white kitten) at the Museum Haus Konstruktiv.

They position Knoebel’s work in a dialogue with the historical legacy of constructive, concrete, and conceptual art. Along with many photographs of the works and the exhibition itself, the catalog also features texts by Sabine Schaschl, Max Wechsler, and Beat Wismer.
