Sports Illustrated is cashing in by offering a poster version of one of their covers for the first time in history. Of course they've decided to mass produce the cover with Michael Phelps and his 8 gold medals against his sexy bare skin.

Phelps, of course, made history in Beijing when he won 8 gold metals in a single Olympic games breaking Mark Spitz's record.

He is expected to make millions and millions and millions in endorsement deals.
