Mary Heilmann in ‘Paintings on Paper’ at David Zwirner Gallery

Mary Heilmann’s two acrylic on paper pieces, both titled ‘Negative Space,’ in David Zwirner Gallery’s summer ‘Paintings on Paper’ group exhibition look like sections of the gallery wall coming forward into the viewer’s space and casting impossibly dark shadows behind, a clever illusion created with simple means. (In Chelsea through August 15th).

Mary Heilmann, Negative Space One, 11 ½ x 11 ½ inches (left) and Negative Space Two, 12 x 15 inches, both are acrylic on handmade paper, 2014.
