Here's a cool piece of Alfred E. Neuman memorabilia. Produced in 1991 by the National Security Agency (NSA), this is their 1991 "Security Awareness" poster. Each year, the NSA produced a double-sided "Security Awareness" poster, each with a different theme. In 1991, they chose Alfred E. Neuman to be their poster boy. This poster measures approx. 17" by 22". The back of the poster (not pictured) features Santa Claus and a couple of elves working in his workshop.
