California-based artist Raymond Pettibon began making his signature ink-wash drawings -- combinations of cartoon-like images with short, enigmatic texts -- in the 1980s. Since then he produced thousands of drawings in his unusual drafting style; framed or pinned directly on the wall, they are often combined by the dozens in no discernible order, like a giant scattered notebook. With solo exhibitions worldwide including a retrospective at The Museum of Contemporary Art, Los Angeles (1994), Pettibon is considered one of the world's most significant innovators of figurative art.
