Two uncommon posters related to the Lunar Orbiter 1, the first American spacecraft to orbit the moon, 15 x 17.5 and 45.75 x 20.5, with the smaller poster featuring a “Geometrical Perspective of First Earth-Moon Photo,” with detailed mission information relative to the spacecraft, its camera, and the time of exposure; the larger poster contains a panoramic view of the Earth as viewed from high above the lunar terrain, with lower caption reading: “Historic First Photo of Earth from Deep Space / Taken August 23rd, 1966 by NASA—Boeing Lunar Orbiter I, Distance from Earth-232,000 mi.—Altitude above Moon-730 mi.” Both are rolled and in very good to fine condition, with scattered creasing, and slight edgewear to larger poster.
