Raymond Pettibon as a contemporary American artist best known for his drawings combining images and text. He often depicts violent subject matter with ironic humour, and an anti-authoritarian streak is evident in much of his work. His black and white images, rendered on white paper with India ink, are his most well-known, but he also uses watercolours, pencils, gouache and acrylics. He is influenced by cartoons as much as the paintings of Edward Hopper and Francisco Goya. William Blake is also a notable inspiration. Pettibon came to prominence through his work with seminal punk rock and Avant Garde music groups like Sonic Youth and Black Flag, for whom he designed a “four bars” logo in the 1970s that has since become iconic.
