In the U.S, artists in the mid-1950s began to create a bridge to Pop. Strongly influenced by Dada and its emphasis on and everyday objects, artists increasingly worked with college, consumer products, and a healthy dose of irony. Jasper Johns reimagined iconic imagery like the American flag. Robert Rauschenberg employed silk-screen printings and found objects, and Larry Rivers used images of mass-produced goods. All three are considered American forerunners of Pop.
