"The CND sign was designed in 1958 by Gerald Holtom[5] and in the following decade became an international peace symbol. *It is based on the semaphore symbols for "N" and "D" (for Nuclear Disarmament) within a circle.* Holtom later said that it also symbolised "an individual in despair, with hands palm outstretched outwards and downwards in the manner of Goya's peasant before the firing squad."
