Between 1966 and 1969, Imi Knoebel worked on a series of black-and-white paintings with lines, now seen to mark the beginnings of his development as artist. The so-called Linienbilder , 90 panels in all, explore the various ways of structuring the picture surface in both single and composite works, taking Malevich's Black Square as a muse. Also included are documentation of related sculptures and installations.
