The USPS is destroying its entire run of “Just Move” stamps. The President’s Council on Fitness was concerned that postage stamps would encourage kids to go out and do handstands without helmets:
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.
Hopefully, the next iteration will include bicycling as an activity.
