Pop art is an art movement that emerged in the United Kingdom and the United States during the mid-to-late 1950s. The movement presented a challenge to traditions of fine art by including imagery from popular and mass culture—including advertising, comics, product packaging, celebrities, and everyday consumer goods—into painting, sculpture, and printmaking. By elevating the banal, the kitsch, and the mass-produced to the status of high art, pop art blurred the boundaries between high and low culture. It is also associated with the artists' use of mechanical means of reproduction or rendering techniques. In pop art, material is sometimes visually removed from its known context, isolated, or combined with unrelated material.
