Sol LeWitt, American, 1928 to 2007, watercolor painting on paper depicting an abstract composition, 1981. Signed and dated, lower right. Framed. Sol LeWitt is known for Conceptual sculpture, geometric design wall painting. Known for his modular white cube sculpture, geometric drawings and abstract design paintings including many wall paintings that took teams of people to execute, Sol LeWitt was a major promoter of dominant post World War II Conceptualism and Minimalism. He used geometric shapes and lines to challenge his viewers, and sometimes they seemed logical and other times they seemed to have no basis in either reason or reality. One of a kind artwork.
