JOHN GLENN POSTAL COVERSIGNED.
Postal envelope with an Art Craft cachet featuring images of John Glenn, a Mercury Atlas launch, and spacecraft in earth orbit. A First Day of Issue Cape Canaveral postmark dated February 20, 1962 is on a block of four Project Mercury stamps. The envelope is displayed between paragraphs of a Typed Letter Signed by Stafford.
Thomas P. Stafford's provenance letter reads: "The Mercury envelope displayed below comes from my personal collection. The envelope was postmarked the day of John Glenn's launch and flightFebruary 20, 1962. The envelope has been signed by John and two other Mercury astronautsGordon Cooper and Deke Slayton. I was selected by NASA in 1962 to be a member of the second group of astronauts, a few months after John's flight. I later flew with Deke on the Apollo-Soyuz mission during July 1975. It was a flight of cooperation with the Russians in contrast to the 'space race' of the 1960s."
