These black rubber hand shapes are forms used in the construction of Apollo pressure gloves. They were made from a cast of the astronaut's hands, and were inserted into a nylon glove and then dipped in a rubber/neoprene compound. The result of the dipping process became the interior pressure bladder of both intra-vehicular (IV) and extra-vehicular (EV) gloves used during the Apollo program.
These forms were made using a model of astronaut Jack Swigert's hands, and were transferred to the National Air and Space Museum from NASA in 1976.
