By 1979 Barbara Kruger stopped taking photographs and began to employ found images in her art, mostly from mid-century American print-media sources, with words collaged directly over them. Her 1980 untitled piece commonly known as "Perfect" portrays the torso of a woman, hands clasped in prayer, evoking the Virgin Mary, the embodiment of submissive femininity; the word “perfect” is emblazoned along the lower edge of the image.
These early collages in which Kruger deployed techniques she had perfected as a graphic designer, inaugurated the artist’s ongoing political, social, and especially feminist provocations and commentaries on religion, sex, racial and gender stereotypes, consumerism, corporate greed, and power.
During the early 1980s Barbara Kruger perfected a signature agitprop style, using cropped, large-scale, black-and-white photographic images juxtaposed with raucous, pithy, and often ironic aphorisms, printed in Futura Bold typeface against black, white, or deep red text bars. The inclusion of personal pronouns in works like Untitled (Your Gaze Hits the Side of My Face) (1981) and Untitled (I Shop Therefore I Am) (1987) implicates viewers by confounding any clear notion of who is speaking. These rigorously composed mature works function successfully on any scale. Their wide distribution—under the artist’s supervision—in the form of umbrellas, tote bags, postcards, mugs, T-shirts, posters, and so on, confuses the boundaries between art and commerce and calls attention to the role of the advertising in public debate.
In recent years Barbara Kruger has extended her aesthetic project, creating public installations of her work in galleries, museums, municipal buildings, train stations, and parks, as well as on buses and billboards around the world. Walls, floors, and ceilings are covered with images and texts, which engulf and even assault the viewer. Since the late 1990s, Kruger has incorporated sculpture into her ongoing critique of modern American culture. Justice (1997), in white-painted fiberglass, depicts J. Edgar Hoover and Roy Cohn—two right-wing public figures who hid their homosexuality—in partial drag, kissing one another. In this kitsch send-up of commemorative statuary, Kruger highlights the conspiracy of silence that enabled these two men to accrue social and political power.
