Rauschenberg was keenly interested in the iconography of American popular culture. He eschewed the emotional style of the Abstract Expressionists without losing the latter’s expressiveness by developing a style that stressed collage and used atypical materials like house paint, as well as techniques such painting with a tire dipped in ink. He expanded his collages by incorporating three-dimensional objects, which he referred to as “combines.” This groundbreaking technique contributed to the course of modern art and creative expression. The works are sometimes called Neo-Dada. Rauschenberg’s fascination with popular imagery and his anything goes aesthetic indisputably influenced Pop Art, which would mimic the look of popular culture as opposed to Rauschenberg’s more subjective renderings.
