A giant plastic bust of Lenin was found in Antarctica. Which reminds me that I must see if I can find out more about the Lenin medallions on the moon.
Later: Correction! Only some of them had Lenin on. They seem to be called “pennants” since they have a trailing ribbony thing, but they look a lot like explodey metal soccer balls. And having just seen two strange re-cuttings of a USSR SF film about landing on Venus, I am less surprised to see that the pennants made it to Venus, too.
