This article intends to investigate the oeuvre of the American contemporary artist Barbara Kruger, contextualizing the birth and development of installation, and the so-called "Site Specific Works", tools frequently used by this artist. Some of her artistic matrixes will also be investigated, as well as the fruitful dialogue established with a certain tradition, in order to produce what I consider to be a combative and composite art, one that amalgamates and refunctionalizes elements of advertising, visual arts, and photography.
