Six Lithographs (Serie von 6 Lithographien) is a complete portfolio of six works created by Fred Sandback in 1975, published by Edition Heiner Friedrich in Munich, in an edition of 25. Each print is signed, dated, and numbered by the artist in pencil, reflecting Sandback's meticulous and deliberate approach to his practice. The suite exemplifies his characteristic exploration of line and spatial delineation, translating into the lithographic medium the same tension between form and void that defined his sculptural installations.
