Conan the Small?
7′1″ 275 pound Wilt Chamberlain
6′2″ 240 pound Arnold Schwarzenegger
7′0″ 450 pound Andre the Giant
Arnold looks like miniature and this was right around when he was winning all of his Mr. Olympia Contests. This shot was taken on the set of Conan the Destroyer; Wilt plays Bombaata, and Andre plays Dagoth.
