Supremely desirable flown mid-sized American flag carried into lunar orbit aboard the CM Endeavour during the Apollo 15 mission, 11.5˝ x 7.75˝, signed and flight-certified in the bottom white stripe in black ballpoint, “Flown to the moon Apollo 15, July 26–August 7, 1971, Al Worden, Apollo 15 CMP.” Attractively double-matted and framed with a signed certificate of authenticity from Worden, who writes: “I hereby certify that the United States flag included with this letter went to the moon aboard Apollo 15 in the spacecraft ‘Endeavour.’ It remained in the command module during the lunar orbit phase of the flight. Apollo 15 was the fourth manned lunar landing mission, carrying for the first time a lunar rover and a Scientific Instrument Bay in the Service Module. The flight was launched on July 26 and splashed down in the Pacific Ocean on August 7, 1971, logging flight time of 295.2 hours and a distance of over 1.4 million miles. Dave Scott and Jim Irwin explored the region of Hadley Rille for three days while I conducted scientific experiments in orbit. On the return to Earth I performed a 38 minute Extra Vehicular Activity (Spacewalk) to recover film that had been exposed during the flight. Apollo 15 has been declared the most scientific flight in the Apollo series.” In fine condition. A fine example of one of the most highly sought-after flown formats.
