In 1967, to celebrate the 50th anniversary of the October revolution, young people across the USSR buried time capsules with letters to future Soviet people, to be unearhed in 2017.
Excerpts from my favourite one:
We, the communist youth of the 60s, can’t imagine life without creative struggle and hard work to build communism - which for you is a living reality.

You didn’t have to chant “Shame on Israeli agressors!”, you didn’t have to protest the criminal war in Vietnam, you didn’t have to read about attacks on the Cuban revolution in your newspapers. All those events, contemporary for us, must seem so distant to you. Your children won’t play with rusty shells and casings they find.
