Frank Stella has been a major figure in American art since the late 1950s when he created black, monochrome paintings whose stark reductionism launched the minimalist movement. In the 1960s he continued to expand geometric abstraction by exploring various formal strategies, such as the use of shaped canvas. Drawing was crucial throughout this development as Stella made sketches to investigate new formal and conceptual possibilities. The nine drawings in this series from the 1960s reflect his evolution from the insistently repetitive geometry of his early works into a greater range of pictorial and spatial relationships of abstract forms. Such working drawings are representative of issues of process and series that were important aspects of the art of the 1960s.
