    Mercury Seven Astronauts: Echo I Commemorative Certificate Signed by All. This First Day Cover bearing a plate block of the 4¢ "Communications for Peace/ Echo 1" stamp, cancelled December 15, 1960, at Washington, DC, with an Artcraft cachet is mounted onto an 11.75" x 8.75" certificate with a 3" x 1" piece of Mylar Balloon Material like that used in the creation of the Echo Satellite. The certificate is signed by each of the original seven Mercury astronauts: "Walter M Schirra Jr", "Alan B Shepard Jr", "Donald K Slayton", "Virgil I Grissom", "John H. Glenn Jr", "Gordon Cooper" and "Scott Carpenter". Double matted to an overall 16" x 13". Some light discoloration around the edges from the mat, some fading to the Slayton and Grissom signatures, overall very good. Also included is an Echo 1 50th anniversary philatelic cover.

    Echo was NASA's first communications satellite, a passive spacecraft based on a balloon design and created at Langley Research Center. It measured 100 feet in diameter and when deployed in orbit, bounced signals from one point on Earth to another.
