Flown American flag patch carried to the lunar surface aboard the lunar module Intrepid during the Apollo 12 mission, 3.5 x 2.25, signed on the reverse in black felt tip, “Alan L. Bean.” In fine condition. From the personal collection of Alan Bean. Accompanied by a lengthy handwritten and flight-certified letter of provenance from Bean, in part: “I hereby certify that the accompanying embroidered American flag was landed on the moon’s Ocean of Storms with Pete Conrad and me in November of 1969. It remained within our lunar module ‘Intrepid’ for 33 hours during which time Pete and I performed 2 moonwalks. We then lifted off the moon to return to Dick Gordon orbiting in our command module, ‘Yankee Clipper.’ This...flag has been in my personal collection since I returned to planet Earth.”
