Apollo-era blue nylon head cover worn by Jim Creagle, a team member of the North American Rockwell Flight Crew Systems during the Apollo Lunar Program. The head cover is designed similarly to that of a scrub or surgeon cap and features a snap to the backside for four potential fitting sizes. In fine condition, with a couple of trivial marks. Accompanied by a signed letter of authenticity from Creagle, which pictures him and other members of the Flight Crew Systems team wearing their head covers.
