In the 1950s and 1960s the National Security Agency (NSA) cranked out beautiful and captivating posters to remind Americans that keeping secrets was important. These declassified posters were unearthed by Government Attic, via its use of the Freedom of Information Act. Funded by the taxpayer, these vintage NSA security posters from the 1950s and 1960s are in the public domain. Below are all 135 posters. It’s a very big gallery of beguiling, weird, creative, eerie, contemporary and very stylish posters from the Cold War period. Please give it a time to load. And look out for John Travolta, the Mona Lisa and Santa Claus endorsing the art of mass surveillance.
