Bighorn Ram 302 by Andy Warhol is the last of ten works in the Endangered Species complete portfolio from 1983. Warhol often referred to this series as his “animals in makeup,” immortalizing the ten species in the Pop Art canon. Endangered Species was commissioned by gallerists Ronald and Frayda Feldman (who are also known as environmental activists) in order to increase consciousness of threatened animal populations and habitat destruction.
