Mauritania  1972
Luna 16.  Luna 17/Lunokhod 1
Another nice pair of illustrations of Luna 16 and 17 from a French colony (see also the pair from Chad by the same designer, Jean Pheulpin). The vertical stamp shows the Luna 16 ascent stage taking off from the surface of Mare Fecunditatis. The other shows Lunokhod 1 rolling down a ramp off the Luna 17 landing stage near the western shores of Mare Imbrium, where it landed in November 1970.
