A monumental inflatable screw appears to drift upward against a stark white ground in this lithograph by Claes Oldenburg, one of Pop Art's most inventive sculptors. True to his signature practice of transforming hard, utilitarian objects into soft, malleable forms, Oldenburg renders the mechanical fastener as a buoyant, almost whimsical shape that defies its industrial origins. The work on Arches Roll paper retains full margins, emphasizing the expansive, floating quality of the image and the artist's playful subversion of scale and material expectation.
