Butch Umbenhauer and Alan Kirk wrestled each other on the AMG mats in 1969. Here they are in Physique Pictorial Vol 18 No. 1 (Jan, 1970) to promote the film. Mizer gave Butch a star of approval, but warned us the guy was a thief. Alan got a big question mark for his analysis, meaning Mizer didn't know much about him. Fortunately, Mizer did tell us Alan was generously endowed...if we didn't notice. 😋
