Influenced by Stuart Davis’s Cubist-inspired paintings, Ad Reinhardt’s early work features canvases covered in colorful and asymmetrical geometric forms, such as Number 43 (Abstract Painting, Yellow) (1947). Reinhardt’s collages are similarly complex, with layers of printed paper cut and pasted in irregular rectilinear forms. His own influence on Minimalism is foreshadowed by his later monochromatic paintings, most notably his series of black abstracts that abandoned gesture in favor of smooth brush strokes and subtle, at times barely noticeable, grids.
