Barbara Kruger is an American conceptual artist. Much of her work consists of black and white photographs overlaid with declarative captions in white-on-red Futura Bold Oblique or Helvetica Ultra Condensed. Much of Kruger’s work engages the merging of found photographs from existing sources with pithy and aggressive text that involves the viewer in the struggle for power and control that her captions speak to. In their trademark white letters against a slash of red background, some of her instantly recognizable slogans read “I shop therefore I am,” and “Your body is a battleground.” Much of her text questions the viewer about feminism, consumerism, and individual autonomy and desire, although her black-and-white images are culled from the mainstream magazines that sell the very ideas she is disputing. Kruger stated that “I work with pictures and words because they have the ability to determine who we are and who we aren’t.” Kruger’s style of displaying her work has not always conformed to the conventional. As well as appearing in museums and galleries worldwide, Kruger’s work has appeared on billboards, buscards, posters, a public park, a train station platform in Strasbourg, France, and in other public places.
