Flown embroidered Gemini 12 insignia patch carried on the mission, measuring 3˝ in diameter, affixed to a letter of provenance on Gordon Cooper's personal letterhead, signed in blue felt tip, "Gordon Cooper." In part: "The crew emblem displayed with this letter was carried into space on the Gemini XII mission during November 11 to 15, 1966. I was back-up commander for the flight crew of James Lovell and Edwin E. 'Buzz' Aldrin. Gemini XII docked with an Agena target vehicle and Buzz made a few spacewalks. We finally figured out how to do spacewalks the right way by that time and Buzz performed his assigned tasks beautifully. Gemini XII was a mighty fine ending to a flight program that made ten successful manned space flights. I then moved over to the lunar landing effort and was assigned as back-up commander for the Apollo 10 mission. That flight demonstrated all the steps needed for the first lunar landing by Apollo 11 except for the final 50,000 feet to the surface. I then expected to have a mission assigned to me for a lunar landing flight but management 'politics' and a 'tight' alliance between some of the Original Seven guys never allowed that assignment to occur." Displayed with a color photo of the Gemini 12 spacewalk, signed in blue felt tip, "Gemini XII EVA, Nov. '66, Buzz Aldrin," matted to an overall size of 19.25 x 12.75. In fine condition, with a small surface scratch to the signed photograph.
