A Global Peace sign, with the earth contained within, forms the 'O' in the emphatic 'WORLD PEACE' slogan. A hippie mantra, and a state of affairs (politically, socially and personally) we strive for.
The peace sign is constructed of the semaphores representing "N" and "D" for Nuclear Disarmament. It was designed as a symbol for the Ban the Bomb movement initiated by the UK's Campaign for Nuclear Disarmament back in the 1950s. Later, during the Vietnam anti-war movement, it would become a hippie symbol for general peace, pacifism and peaceful coexistence.
