When I think of works on paper, images of cutting-edge creations by process-based contemporary artists come to mind, along with thoughts of shows like the recent Cumberland Gallery exhibit Without Borders, which featured gallery artists hanging frameless finished works (many of them paper). But artists have always made use of paper in their preparatory sketches as well as in fully realized masterpieces. This new show at Haynes Gallery examines a broad spectrum of artists and works in its celebration of the substrate. Gallery owner Gary R. Haynes describes the inclusion of a selection of Winslow Homer’s letters, wood engravings and original drawings as “the exhibit’s cornerstone,” but the show also features a nude by John Singer Sargent and black-and-white portraits by photographer Yousuf Karsh. While all of that may sound appealing, my visit to the show will have everything to do with their promise to display a Jamie Wyeth sketch of Arnold Schwarzenegger on corrugated cardboard.
