Girl Gives A Victory Hand

• Vietnam War, victory and peace
U.S. President Richard Nixon used it to signal victory, an act which became one of his best-known trademarks. He also used it on his departure from public office following his resignation in 1974.
A similar sign was used in protests against the Vietnam War (and subsequent anti-war protests) and by the counterculture as a sign of peace. Because the hippies of the day often flashed this sign (palm out) while saying "Peace", it became popularly known (through association) as the peace sign.
