Peace Flag3' x 5' Peace flag with grommets and double stitched edges to reduce fraying. Our Design: In the 1950s the "peace sign", as it is known today, was designed by Gerald Holtom as the logo for the British Campaign for Nuclear Disarmament (CND). The symbol is a super imposition of the semaphore signals for the letters "N" and "D", taken to stand for "nuclear disarmament". I took the peace sign symbol, made it nice and thick and slapped it on a white field.
