Created in 1966, this portfolio by Josef Albers consists of ten silkscreen prints exploring his lifelong fascination with color interaction and perception. Each variant presents subtle shifts in hue and tone within precise geometric compositions, demonstrating how the same structural framework can produce dramatically different visual experiences. Published by Ives-Sillman in New Haven, this limited edition of 300 signed sets is housed in an original cloth-covered slip case, making it a distinguished example of Albers' systematic yet deeply nuanced approach to color theory.
