Among the items issued to astronauts are velcro-backed leather name tags that can be attached to flight suits. This name tag is a spare for Shuttle astronaut Jerome "Jay" Apt, who was a mission specialist on STS-37, STS-47, STS-59, and STS-79.
NASA transferred a number of spare astronaut name tags to the Museum over the years, this one coming in 2001.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
