Clear, perfect ballpoint signatures, “John Lennon” and “Yoko Ono Lennon,” on the correspondence side of a 6 x 4 postcard with a color photo of a BOAC Rolls-Royce 707 Jetliner. Accompanied by a letter of provenance from the original owner, who explains that, while working as an air steward for BOAC, he obtained the signatures personally on a New York–to–London flight, circa 1974. A few faint, tiny spots (away from signatures) and neat collector’s ink notations, otherwise fine, fresh condition. Auction LOA Roger Epperson/REAL and R&R COA.
