"Extremely limited edition" in this case means "you can't have one."

Artist Paolo Rivera has more reason than most to take pride in the box office success of Iron Man 3: He has blogged before about how thrilled he was that an early poster for the movie was based on his cover for Iron Man #63, and now he's written about his emotional investment in seeing the film for the first time.

This would be noteworthy enough in its own right, but the piece is accompanied by a spectacular print that he's painted exclusively for the cast and crew of the production. Rivera had previously produced a suitably 1940s-looking poster for those working on Captain America: The First Avenger, and the Iron Man 3 print is designed to resemble a battered old pulp novel (suitably enough, given the styling of the end credits animation and the origins of Robert Downey Jr. and Shane Black's previous collaboration). This is an extremely cool piece of art, and as exclusive as any limited edition poster you're likely to see — do not expect to see copies of this one ever turning up on eBay (unlike, say, the gougers flogging his "Precious Cargo" at a helluva mark-up).
