Guy Colwell (b. 1945, Oakland, California) is a painter and comics artist best known for his underground comix series Inner City Romance , which once sold 50,000 copies an issue. It was inspired by the two years Colwell spent at McNeil Island federal prison for draft refusal in the late '60s. He also illustrated the underground paper Good Times , and worked as a colorist for and contributor to a number of underground comix projects, before focusing on his work as a painter. Today he is well known for his political paintings, including Litter Beach and The Abuse , as well as wildlife murals, like the 700-square-foot rainforest wall Colwell painted for the Oakland Zoo.
