Peace This internationally recognized symbol was designed and completed on 21 February 1958 by Gerald Holtom, a professional designer and artist. The symbol itself is a combination of the semaphoric signals for the letters "N" and "D," standing for Nuclear Disarmament.
The peace flag is a series of seven rainbow stripes with the word for peace printed in the center. Previous Italian peace flags had featured a dove drawn by Pablo Picasso; the new design first appeared in an Italian peace march as early as September 24, 1961. The flag was often flown from balconies in Italy by citizens opposed to the Iraq war. Its use has spread to other countries as well, with the Italian "pace" replaced with its translation in various other languages. The seven-color peace flag is not to be confused with the similar six-color Gay pride flag which does not have turquoise, and has red at the top instead of the bottom, the difference is very little and you can found here both symbols.
