Gary Grimshaw is a graphic artist and poster designer specializing in the music business. He was born on February 25, 1946 in Linclon Park, Michigan. His high school best friend was Rob Derminer (Rob Tyner, stage name) who later started a band called the MC5. Gary did many images for the MC5 and worked on staff with The Rainbow Peoples Party, the Detroit Artists Workshop, Translove, and at the Hill House in Ann Arbor, Michigan (a commune) not in that order. During the heyday of Detroit's Grande Ballroom, Grimshaw was one of the two primary psychedelic poster artists contracted by promoter and DJ Russ Gibb (the other was Carl Lundgren). Grimshaw was active in the anti-war movement and the White Panther Party. He was Minister of Art for the White Panther Party which modeled itself after the Black Panthers.
In 1969, the Michigan Court of Appeals, acting on the application of Gary Grimshaw, ruled that the city of Detroit's obscenity ordinance was unconstitutional, and overturned Grimshaw's conviction by a lower court on obscenity charges.[1]
