Studied art at the University of Minnesota 1953, then at the Art Students League, New York, 1955-6. Supported himself for several years by working as an industrial painter and sign painter, his work in 1958-60 including painting the enormous billboards in Times Square. Met Indiana, Rauschenberg, Johns and Ellsworth Kelly. His early paintings Abstract Expressionist, but began in 1960 to work with bizarre juxtapositions of fragments of immense, sometimes unrecognisable images derived mainly from advertisements.

Painted some very large pictures, including a mural for the New York World's Fair 1964 and a huge painting 'F-111' 1965, over 26 metres long.
