Christina Ramberg (21 August 1946 – 1995) was an American painter associated with the Chicago Imagists, a group of representational artists who attended the School of the Art Institute of Chicago in the late 1960s. The Imagists took their cues from Surrealism, Pop, and West Coast underground comic illustration, and their works often included themes of female sexuality. Ramberg depicted partial female bodies (heads, torsos, hands) often in submissive poses in undergarments, imagined in odd, seemingly erotic predicaments. Biography.
