Among the items issued to astronauts are velcro-backed leather name tags that can be attached to flight suits and jackets. This name tag is a spare for astronaut John W. Young. He commanded two missions aboard Space Shuttle Columbia: the first Shuttle flight in 1981(STS-1) and the first Spacelab flight in 1983(STS-9). Before that he had flown on two Gemini missions (1965, 1966) and two Apollo missions (1969, 1972). John Young was the first person to fly in space six times.
NASA transferred a number of spare astronaut name tags to the Museum over the years, including this one in 2000.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
