Back in the days when GAY only meant "happy and joyous", and TOP only meant the upper part of anything, someone dreamed up a product called GAYTOP!  I just had to share this with you on my blog.
Next is an interesting German picture which combines the heroic male nude statues (yum!) of Hitler's Third Reich with the German eagle symbol. Wouldn't it be cool if they could make airplanes that looked like this? 
Next, another underwear ad in color. This guy might "feel like a million", but his crotch seems "dead and buried"! Poor man.
Isn't it interesting, that in the 1950's and 1960's, only women could be sexy? Women wore brassieres that shoved their chests out at the world. Here's a famous picture of Italian actress Sophia Loren ogling the "practically-falling-out-of-her-dress" boobs of Jayne Mansfield. Mamma mia.
In those days, men weren't allowed to be sexy. Like the man in the underwear commercial above, we guys were expected to "strap ourselves in" so that all traces of having male genitalia would remain obliterated. Jantzen swimwear ads never vary; the men in them have flat, flat crotches. And the waists are so darn high! 
Then we have "The Catalinas", named after that island off the coast of Southern California. The colors are nice. The material looks great. But the swimsuits have NO sex appeal whatsoever! It must have been boring to go to the beach in those days, surrounded by a bunch of "castrated-looking" guys, with no bulging crotches or bouncing buttocks to enjoy looking at. Ho hum.
Then, at the end of the 1960's, things started to change, and men were finally allowed to be sexy. Just look at these paperback novels from back then. Here are men with nice big packages in their bulging swimwear/underwear. It must have been a fantastic and delicious surprise to see these books on sale for the first time! Animan's World celebrates the natural man, "letting it all hang out"!
