The sign accompanying the A7L suit. It reads
The Apollo Space Suit
This suit with its backpack, designed and created primarily for extra-vehicular
activity, enabled the lunar astronauts to dispense with the umbilical hose of
the type used on the Gemini "spacewalk" and to roam freely over the lunar
surface. This EVA space suit system was one of the most complex and difficult
crew-equipment development programs yet undertaken in the manned space flight
era.
