Genre: Information/Explanation

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 to the surface .
