The Soviet Union Used These Posters To Stop Spies In The 1950s

The Soviet Union was known for its intense propaganda art.
Messages varied from inspiring photos of space travel to heavy-handed warnings to potential spies.
Retronaut collected and translated a series of Soviet posters from the 1950s aimed at preventing information reaching U.S. spies inside the U.S.S.R.
1958: “Do not talk! Strictly keep the military and state secrets!”

1953: “Vigilance, our weapons!”

1954: “Gossip, gossip – the hands of the enemy!”
