While a print by Damien Hirst recently fetched £12,655 at auction, that's nothing compared to a copy of Action Comics #1, in which the Man of Steel makes his first appearance (at that time, Superman was simply known as 'The Man of Tomorrow.') The rare comic went for a cool $1 million.

Action Comics #1 came out in 1938 and cost a measly 10 cents. Two years later, the first Superman adaption hit the airwaves. 'The Adventures of Superman' debuted on New York's WOR and ran for 11 years.

Below is the iconic opening:

Presenting the transcription feature: Superman. Look up in the sky! It's a bird, it's a plane, it's Superman! Yes, it's Superman--strange visitor from the planet Krypton who came to Earth with powers and abilities far beyond those of mortal men. Superman, who can leap tall buildings with a single bound, race a speeding bullet to it's target, bend steel with his bare hands, and who, disguised as Clark Kent, mild-mannered reporter for a great metropolitan newspaper, fights a never-ending battle for truth and justice.

The sale was conducted by ComicConnect.com. It broke the previous comic book record of $317,200, which was also for a copy of Action Comics #1. There are estimated to be only 100 copies of this comic in existence and it looks like there's another one up for auction soon.
