Linn’s Stamp News reports that the US Postal Service will destroy the entire press run of a stamp series aimed at getting children to be more active. According to Linn’s reporter Bill McAllister, three of the stamps in the fifteen stamp series raised safety concerns among sports figures on the President’s Council on Fitness, Sports & Nutrition. The stamps in question depicted children performing a cannonball dive, skateboarding without kneepads, and doing a headstand without a helmet. The unsafe depictions came to light after USPS Marketing chief Nagisa Manabe asked Michelle Obama to take part in a first day ceremony for the stamps. That was apparently the first time the stamps had been reviewed by the Sports Council.
