American Idol winners are now available on stamps.

The special edition postage will feature previous winners Kelly Clarkson, Ruben Studdard, Fantasia, Carrie Underwood, Taylor Hicks and Jordin Sparks, as well as the soon-to-be-decided Season Seven winner.
AMERICAN IDOL stamps will feature exclusive designs for each of the 50 states.
Only 100,000 sheets of PhotoStamps will be issued weekly, and each state will have its own design featured on 2,000 of the sheets. AMERICAN IDOL PhotoStamps are first-class rate postage valued at 42 cents each, and each sheet (20 PhotoStamps per sheet) will retail for $19.99.

Net proceeds from the sales of the exclusive PhotoStamps will benefit IDOL GIVES BACK.
