These posters designed by the NSA emphasizing the importance of security and secrecy to their employees are amazing. Declassified in mid-April 2018, most of the posters were produced in the 50s, 60s, and 70s and look as though they were cooked up by Salvador Dali or the Dadaists. Or even Mad Magazine. I mean:

What fantastic design artifacts of that era. Many of them appear to be remixes/riffs of contemporary ad campaigns and messaging…you could easily imagine a security-themed distracted boyfriend or American Chopper poster hanging in today’s NSA offices.

I had a difficult time choosing just a few of these…many more are available in this PDF. (via hn)
