Commemorative cover, 6.5 x 3.5, honoring the US Navy Recovery Force, Pacific, signed in blue ballpoint. The Apollo 8 stamp has been postmarked USS Hornet, July 24, 1969. In very good condition, with faint scattered toning and the printed portions of the envelope almost completely faded. Armstrong is notoriously difficult to find on philatelic covers.
