American artist Robert Rauschenberg's early works anticipated the pop art movement. He is best remembered for his "Combines" of the 1950s, in which non-traditional materials and objects were employed in innovative blends. One of his first and most famous combines was Monogram (p. 188), in which the unlikely mix of a stuffed angora goat, a tire, a police barrier, the heel of a shoe, and a tennis ball alter the course of modern art. The work in this book will stop viewers in their tracks, just as they did in mid-twentieth century.
