The sign that is universally recognized as the peace sign was designed in 1958 by artist Gerald Holtman for the British nuclear disarmament movement.  Holtman combined the semaphore signal for "N," which is formed by holding two flags in an upside-down "V," with the letter "D," which is made by holding one flag straight up and one straight down.  The "N" and "D" represent nuclear disarmament.
