To key into First Lady Michelle Obama’s “Let’s Move!” campaign, a “Forever” stamp series has been created by the U.S. Postal Service. The 15 physical activity stamps had made it to the printer, but were put on hold after the President’s Council on Fitness Sports and Nutrition and officials at the Let’s Move campaign reviewed them and deemed three to be promoting unsafe moves -- a swimmer cannonballing into a pool (shown), a skateboarder sans kneepads and a kid doing a handstand without wearing a helmet. The decision to destroy or issue the postage stamps will be made next year.
