Communication Carrier Assembly cap, commonly known as the 'Snoopy' cap, manufactured by ILC during the Space Shuttle era, with the parts label above the right earcup marked in red felt tip and reading: “Comm. Carrier Assembly, S/N 0101-10001-, Size 05, Date 12/96, NAS9-17873, ILC Dover 74897.” In fine condition, with wear to Beta cloth and some cracking to inner leather ear pads. These caps were designed to secure the earcups and microphones the astronauts used for communications, and the design was largely unchanged from the 'Snoopy' cap made famous during the Apollo era.
