I've started a modest collection of goofy old comic book ads. Stuff like Charles Atlas offering you a "He-Man Body" and the 204 piece soldier set. When I can find 'em, I'll eventually ad the Bruno Sammartino training ad, Arnold Schwarzenegger's Atlas ad, and the CLASSIC Rick Barry/Dr. J Spalding Streetball ad. But for now, it's a decent start.

Check 'em out at:

Did anyone ever actually participate in those "sell crap for crap" crap?

My big brother did... around 1981. I gave him shit about this "Captain O" card and he kicked my ass.

Added two new entries. Including, THIS AMAZING PICTURE
(okay, it's only El Gigante, PN News, Ron Simmons and friends)
