Homemade commemorative cover on a 6.5 x 3.5 airmail envelope. Bold collector’s handwritten cachet reads, “Commemorating ‘Project Mercury’ outer space launching of Astronaut John Glenn, USMC on Feb. 20, 1962 at Cape Canaveral, Florida,” and inscribed in the same hand, “To Geo. L. Kerns, Act. Chaplain, USN—WW I,” and signed in black ink over the stamp by Glenn, “J. H. Glenn, Jr.,” and signed vertically by Thomas Lanphier, the fighter pilot who shot down the plane carrying Admiral Yamamoto. In fine condition, with a bit of light contrast to Glenn’s signature and additional information and clipped photo affixed to reverse. Pre-certified Steve Zarelli and RR Auction COA.
