The very first Superman comic ever created is going up for auction. The 1938 handmade prototype is one of only two known to be in existence. "It's an "ashcan" copy: a handmade prototype created specifically for trademarking purposes," said its owner, Gary Colabuono. In the 1930s, comic book publishers used ashcans to trademark their character and logos. Superman was originally one of several characters featured in Action Comics, a series published by DC (Detective Comics). When DC publisher Harry Donenfeld realized kids were clamoring for Superman, he decided to give the super hero his own series. The special comic book is offered at http://www.Mastronet.com. Find it under Lot #456 of the Americana Auction until October 22.
