ILLUSTRATED: A. Sokolov & A. Leonov, Ждите нас, звёзды! [Stars, wait for us!], 1981.
A wonderful Soviet-era conceptual piece, painted just two years before the first lunar landing during the Apollo missions. Sokolov depicts two cosmonauts preparing for a rocket launch to the planet Mars, from a Cosmodrome set up on Phobos, the closer of Mars' two satellites.
