After a short stay in Los Angeles after he graduated, David Mann returned to Kansas City and bought a 1948 Harley-Davidson. About the same time he created his first painting, “Hollywood Run.” The Harley and the painting were entered the 1963 Kansas City Custom Car show where Tom Fugle and Harlan “Tiny” Brower took an interest in his art. They showed a photo of Hollywood Run to Ed Roth, who was publishing Choppers Magazine at the time. Roth loved the painting and commissioned as many as 20 original posters for the magazine. Roth put his own copyright on the prints as they were commissioned works, but they were all done by Dave Mann.
Mostly published between 1965 and 1970, they represent some of the iconic artist’s earliest published works.
