Robert Arneson's 1965 sculpture Scale has been acquired by the San Francisco Museum of Modern Art. An iconic work from early in his career, Scale is an example of Arneson’s brand of irreverent Pop and represents an important milestone in the development of Robert Arneson as an artist. Its incorporation of the body as implied subject matter, as well as the use of humor, show Arneson exploring two major elements of his art that would prove to be mainstays of his later work.
