Richard Serra’s “reversal” drawings employ two identical rectangular sheets of paper that are adjoined in a vertical or horizontal format, with the black-and-white areas reversing themselves proportionally top to bottom (or left to right). Vertical and Horizontal Reversals is the most extensive presentation of Serra’s reversal drawings to be published. It reproduces all thirty-three drawings shown in 2014’s exhibition at David Zwirner in New York, including a group of new horizontal reversals.
