Poster Museum, Wilanów

This guide to the Poster Museum in Wilanów, Warsaw, opens with the coded, censorship-dodging visual language Polish artists developed for film and theater posters under communist rule in the 1960s, later dubbed the Polish Poster School. It follows National Museum director Stanisław Lorentz, who quietly gave away thousands of posters from his own storerooms in 1968 to start the world's first museum built solely for posters. Notice the ornate 1848 riding-school facade fronting the modern gallery behind it.
