Etching: Framed; Al Held

Four open boxes hang in midair, and none of them seems bothered.

This etching, Stone Ridge #6, is by Al Held, American, 1928 to 2005, from the United States, about 1984. Held spent much of his career building impossible spaces out of ruled lines, and etchings like this let collectors live with those ideas at a domestic scale. Red, yellow and tan outlines draw long boxes that tilt against one another, while large blue rings turn behind them. Scattered around are small marks of blue, gold, green and dark red. A wide white mat and pale frame keep order at the edges. Forty-seven inches wide by thirty-four and a half high.

Try finding the floor. We have not.
