Here's a nice picture of vintage cars parked next to bodybuilder REG LEWIS (b. 1936). I can't find the date of the image (1960s maybe?) and information about Reg Lewis varies. (Some sources say he was born in California, others say Colorado.) Also, he was not Mr. Universe 1957 as his wife claimed when she and Reg appeared on the November 12, 1959 episode of You Bet Your Life. (Groucho Marx invited 23-year-old Reg to take his shirt off and flex. He did.) A few years later he starred in an Italian film, Colossus of the Stone Age (1962). He subsequently had some bit parts in other films, and was one of the muscle men in Mae West's nightclub act.
