A rare copy of the comic book which introduced Superman to the world is expected to sell for up to $400,000 (£282,685) at an upcoming auction.
Bidding on the "untouched" copy of Action Comics No. 1 will begin on Friday (27Feb09) and continue for two weeks at comicconnect.com. Only 100 copies of the graphic novel are known to exist.
Co-created by Jerry Siegel and Joe Shuster, it sold for a meagre 10 cents (£0.07) when it first hit shelves in 1938.
The comic book's owner, who has not been named, kept the book for 58 years after purchasing it for 35 cents (£0.25).
Comic expert Stephen Fishler tells the New York Daily News, "It's the Holy Grail of comic books. One bidder wanted to trade (me) his Ferrari for the comic book."
