Luna 16 and Luna 17/Lunokhod 1
Two nice illustrations of Soviet automated Moon landers, released as a pair in 1972. The first shows the Luna 16 ascent stage taking off from an improbably rugged Moonscape, while the second shows Lunokhod 1 gingerly crossing an equally improbable crevice in the surface. The inscription at the bottom of the right-hand stamp, ‘Luna XVII’, refers to the Luna 17 lander which delivered Lunokhod 1 to the surface.
