The peace symbol ☮, a.k.a. the nuclear disarmament symbol and the CND symbol, was designed in 1958 for the British nuclear disarmament movement by Gerald Herbert Holtom (1914—1985). The symbol is a combination of the flag semaphore signals for the letters N and D, standing for “nuclear disarmament”.
Since then, ☮ has become a universally recognised peace symbol, without losing its association with 1960s peace movement. This year, the poster for the Carnival of Las Palmas de Gran Canaria was featuring the plasticine “Flower Power” peace symbol complete with Andy Warhol, The Beatles and Yellow Submarine.
