Best known for laying aggressively directive slogans over black-and-white photographs that she finds in magazines, Barbara Kruger developed a visual language that was strongly influenced by her early work as a graphic designer (at magazines including House and Garden, Mademoiselle, and Aperture). Among her most famous pieces are I shop, therefore I am (1987) and Your body is a battleground (1985). Informed by feminism, Kruger's work critiques consumerism and desire, and has appeared on billboards, bus cards, posters and in public parks, train station platforms, and other public spaces. She has also created site-specific installations comprised of video, film, audio, and projection.
