Apollo Training Crew Systems Guide, Course Number A–512C, dated September 1, 1965, 9 x 5.75. Done by North American Aviation, Inc., this guide provides in-depth instructions and training for all aspects of an Apollo mission including space suit assembly, mission experiments, spacecraft lighting and sighting, food, water, hygiene, and survival kit. Signed on the back cover in black ballpoint, “Roger B. Chaffee,” and “Ed White.” Expected handling wear, with scattered creases, toning, and soiling to front and back cover, with none of the flaws detracting from the large signatures, otherwise fine condition. A very interesting and uncommon format, signed by the two astronauts whose deaths were directly tied to this program. RRAuction COA.
