[Work Heroically - The Way to Victory in Space!], 1964. Estimate: $800 to $1,200.
Fifty years ago today, the Soviet space program launched Vostok 1, successfully putting Yuri Gagarin into orbit. The space race was used by the Soviets in their propaganda aimed outside the country—images of cosmonauts and rockets appeared on Intourist posters—and within. A rare poster from the Soviet space program made in 1964 appears in Swann's Modernist Posters auction on May 5th.
Additionally, today marks the 30th anniversary of NASA's first space shuttle launch.
