Flown NASA beta-cloth patch, 4.5 x 4.5, signed in black felt tip by Irwin’s wife, “Flown to the moon on Apollo 15, July 26, 1971, cut from equipment left in Lunar Module by James B. Irwin. Mrs. Mary E. Irwin, wife of the late Colonel James B. Irwin.” Sewn onto a slightly larger piece of cloth. In fine condition, with some trivial soiling and the edges of the cloth backing partially frayed. An incredible relic wisely acquired before the jettison of the lunar module. Provenance: Superior Auction. RR Auction COA.
