After the Second World War ended, a new era began for the United States—an era of cars, television, billboards, pulp magazines, commercialism. Roy Lichtenstein and Andy Warhol embraced work that commented on print, printmaking, and mass production. In 1963, Lawrence Alloway, who helped coin the term “pop,” curated an exhibition at the Guggenheim, titled “Six Painters and the Object.” It marked the beginning of Guggenheim surveys dedicated to the movement’s pioneers: Jim Dine, Claes Oldenburg, James Rosenquist, and Robert Rauschenberg. This exhibition examines their legacy. —Elena Clavarino
