Here you have a WONDERFUL VINTAGE piece of JOHN GLENN and MERCURY PROGRAM MEMORABILIA. Please...SEE THE SCANS! This is the envelope and cachet marking the 13th anniversary of John Glenn's Mercury flight... The cachet is an image of Glenn with President Kennedy and the Friendship 7 capsule. The stamp was cancelled at Cape Canaveral on February 20, 1975! The envelope measures 6 1/2 inches X 3 5/8 inches and this is in very fine shape! The flaw on this is the spotting on the back cover... Take it home with you! GOOD LUCK! Please Check Out My Ebay Store for more great memorabilia! I am happy to send this to any country. 1st class air postage will be charged… More excellent packaging and free 1st class shipping here in the United States! THANKS! 060219
