The work of Swiss sculptor Alberto Giacometti (1901–1966), often compared to that of the Existentialists, contrasted with the avant-garde in that it attempted to equal reality so that a sculpture, like “Observing Head” (1927), would be perceived as if it were alive. Other masterpieces are “The Palace at 4 a.m.” and “1 + 1 = 3”. (M 44186) _ _.
