An admission ticket to an art installation called “Totalitarian Zone,” which was held inside the pedestal of what was once Stalin’s monument in Prague. Dated 18–31 October 1990. I’m pretty sure that’s the space shuttle.
There’s a lovely poster for the same event on the Facebook page of Linhart’s Foundation, which was one of the event’s producers. My thanks to the translator Alex Zucker for pointing the poster out to me.
