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 Robert L. "Hoot" Gibson, who was the pilot for STS 41-B and commander of STS 61-C, STS-27, STS-47, and STS-71.
NASA transferred a number of spare astronaut name tags to the Museum over the years, including this one in 2001.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
