Larry McGlynn’s collection of NASA-related items includes astronaut Edgar Mitchell’s spoon from the Apollo 14 mission, a model of a Lunar Rover, a stopwatch, and space-themed toys.

McGlynn is the owner of the last jockstrap worn on the moon, an unusual artifact worth an estimated $10,000 and part of his vast collection of space memorabilia that includes spacesuits, flags, and flight logs of US and international space missions. McGlynn, 61, began collecting 55 years ago, when his brother’s school science project brought them to Raytheon Co., where they were given a piece of Mylar from the Echo satellite.
