One of the most chilling symbols of the Cold War has to be the black-and-yellow aluminum sign, indicating a nuclear fallout shelter.
The man responsible for the sign, Robert Blakeley, died on Oct. 25, at the age of 95.
The signs — long out of use — can still be found across the country at schools and other buildings designated as public shelters by the government, in the event of a Soviet nuclear strike.
Back in 1961, Blakeley was asked by the US Army Corps of Engineers to come up with a design for the new fallout shelter program.
