The term 'peace signs' can refer to two different symbols. The first is the V-sign, which is made by holding up the index and middle fingers in a V shape. This symbol has been used since World War II as a sign of victory and peace. The second symbol is the dove, which is a bird that has long been associated with peace and harmony. The dove is often depicted carrying an olive branch, a symbol of peace. Both of these symbols are widely recognized as symbols of peace and are often used in protests and other demonstrations for peace.
