Give This Peace Symbol Memory Match a Chance

On Feb. 21, 1958, Briton Gerald Holtom designed the peace sign. Commissioned by the Campaign for Nuclear Disarmament, the symbol is comprised of a circle with two semaphore letters (you guessed it -- N and D, for Nuclear Disarmament). Semaphore is a system of using flags to send info via long-distance (for example -- from one ship to another). In this case, the two letters are used as flags. In other words, it's a long distance (aka global) call to "Give peace a chance."
