Action Comics No 1 issue from 1938, featuring the debut of Superman.

A man in the US has found a rare first edition of a Superman comic book while he was decorating a new house.

David Gonzales from Minnesota, found the Action Comics No 1 edition stuffed in a wall with other newspapers.

He's now put the comic up for auction and it's already attracted bids of more than $100,000.

Only about 100 copies of the first edition are thought to exist, with just a few of them still in good condition.
