Yin and Yang; the opposing forces of good and evil/light and dark/day and night that work in perfect harmony to maintain the balance of power between good and evil/light and dark/day and night. Description: A dear friend, Amy and myself standing in front of an oriental background wearing black and white to represent the two opposing forces of good and evil. Made to look old and worn as though weathered, this picture bears the words 'Yin' and 'Yang' down either side.
