Three Apollo 11 First Day of Issue philatelic souvenirs, each 4.75 x 6, bearing a printed reproduction of the plaque left on the lunar surface, a first man on the moon postage stamp, and two 1969 postmarks, including moon landing cancellation. Each is signed in black felt tip by one of the Apollo 11 astronauts, “Neil Armstrong,” “Buzz Aldrin,” and “M. Collins,” with Aldrin’s also signed by James McDivitt. In very fine condition. Each is accompanied by a full letter of authenticity from Steve Zarelli. A very uncommon offering, as all three crew members were reluctant to sign any type of philatelic material. RR Auction COA.
