The sign accompanying the suit. It reads
This XN-17 suit was manufactured by B.F. Goodrich in Akron, Ohio, in November
1962, and is an adaptation of the Mark IV that was adapted
for use in Project Mercury. The Mark IV
was a standard pressure suit used by naval aviators, and it formed the basis
for the space suits that equipped the first astronauts. Interestingly, each of
the seven Mercury astronauts was provided with three suits specifically
tailored to their physical size. They cost about $5,000 apiece.
