NSA Security Awareness Posters
I have a related personal story. Back in 1993, during the first Crypto Wars, I and a handful of other academic cryptographers visited the NSA for some meeting or another. These sorts of security awareness posters were everywhere, but there was one I especially liked — and I asked for a copy. I have no idea who, but someone at the NSA mailed it to me. It’s currently framed and on my wall.
I’ll bet that the NSA didn’t get permission from Jay Ward Productions.
