I have an old copy of Playboy magazine from 1966, and it's filled with all sorts of interesting art. Here's a nicely-drawn sketch of Dad parading around in his tighty-whities, and as you can see, good manners insist that he keep his "unmentionable body parts" strapped in to the max--the flatter, the better.
This next picture is really something. The image of the all-American man with slim, long legs is understandable, but this is just stretching things all out of proportion!
