Freedom Of Information Requests (FOIA) can be made for all sorts of inquires. Recently Government Attic, a website dedicated to collecting various fascinating Federal Goverment documents, made a strange request. They requested all the NSA security posters from the 1950’s and 1960’s. It took a couple of tries but they succeeded and the NSA released a hefty 73 megabyte file containing 139 pages. Below a sample of posters from that document.
Government Attic has provided the full 139 PDF file located here.
