Robert Rauschenberg

American painter and graphic artist Robert Rauschenberg pioneered the use of nontraditional materials in the creation of artwork, having travelled the world collecting trash and creating collages out of them. He carried that approach to the paintings that he would create in the later in his career, utilizing not just found materials, but also images that he reproduced. This resulted in works that blended many types of imagery and materials together in one space, from rubbish to newsprint. He also often utilized images of recognizable figures, such as President Kennedy, or Coca Cola bottles in his works.
