Flash Gordon by Frank Frazetta

 Yeah, it's actually Buster Crabbe playing Flash Gordon in the 1930s.  When I met him in the 1970s, he still looked amazingly like this, cept for the creases and stash.  This copy is from the back of the amazeballs fanzine Heritage 1A (not to be confused with Heritage 1B, which is even more amazeballs)
