Green Day's official fan club, Idiot Nation, is having a giveaway for their members for a chance to win some exclusive post cards made to promote the American Idiot Tour back in 2005.

The post cards feature some jumping silhouettes and were designed by Chris Bilheimer who has designed much of Green Day's album artwork since 2000's Warning.

Visit GreenDay.com for more info, or if you're a member you can login directly to GDIdtionNation.com. The four winners will be chosen by March 7th so get your entry in by that time.
