Presented in these two albums are crew signed covers for all 153 NASA manned spaceflights, from Alan Shepard's 15-minute Mercury Redstone-3 sub-orbital flight on May 5, 1961, to the Space Shuttle's 124th mission, STS-126, in November, 2008.

365 different astronauts participated in these 153 NASA manned spaceflights in the Mercury, Gemini, Apollo, Skylab and Space Shuttle Programs. Crew size ranged from one in the Mercury Program, to typically 6 or 7 in the 120+ Space Shuttle flights, with one flight, STS-61A, having 8 crew members. There are over 800 autographs applied to the 153 crew signed covers shown here. Most astronauts made more than one spaceflight and, for example, autographs of 7-time Shuttle flier Jerry Ross are found on seven different crew signed covers here.....I acquired these crew signed covers in a variety of ways: most were thru-the-mail requests directly to the crews; some were purchased; and others obtained in trades from other collectors (and three shown here are owned by another collector).....I wish to take this opportunity to thank the hundreds of astronauts who kindly took time to autograph my covers thru the years. Without their kindness and cooperation, collections such as this wouldn't exist. Thank you all.
