Sought-after Gemini 8 launch day cover with a cachet honoring the historic mission which saw the first docking of two spacecraft in orbit, postmarked at Cape Canaveral on March 16, 1966, signed in blue ballpoint by Neil Armstrong and in black felt tip by Dave Scott. In very fine condition, with very faint haloing to Armstrong's signature. Accompanied by a full letter of authenticity from Zarelli Space Authentication.
