The sign by the display. Even though the sign is for the "Prototype Cover
Layer" (which I take to mean the ITMG), the sign is in front of the TLSA.
The sign reads:
SPACE SUIT FASHIONS
MODEL: A7-L Prototype Cover Layer
MATERIAL: Nomex, aluminized mylar, nylon
CONDITION: Never been worn
Is the outside of your suit getting a little worn? This prototype cover
layer will make your suit look like new. Built during the design process for
the Apollo missions, this Nomex suit was a test to see how sections of the suit
would be joined together. A good cover-layer protects astronauts from the
extreme temperatures of space as well as micrometeorite impacts.
