Tom Wesselmann was a leader of the Pop Art movement. He is best remembered for large-scale works, including his Great American Nude series, in which Wesselmann combined sensual imagery with everyday objects depicted in bold and vibrant colors. As he developed in his practice, Wesselmann grew beyond the traditional canvas format and began creating shaped canvases and aluminum cut-outs that often functioned as sculptural drawings. Continuing his interest in playing with scale, Wesselmann began focusing more closely on the body parts that make up his nudes. He created his Mouth series and his Bedroom series in which particular elements, rather than the entire sitter, become the focus. Bedroom Breast (2004) combines these techniques, using vivid hues painted on cut-out aluminum.
