Marvel Studios just announced via the Iron Man Facebook page that they're holding a trivia contest for fans at the Iron Man 3 Twitter account.

The full rules are available here, but the long and short of it is that they'll be asking questions to test your mettle on all things Stark, and that of the correctly-answered questions (submitted via Twitter or e-mail), twenty will be chosen at random to receive an Iron Man 3 promotional package.

The contest runs through Midnight on March 1.
