In 1970, Philip Guston shocked the artworld with his return to figurative painting after being crowned one of the heroes of abstraction. Made a year later, Poor Richard is a series of over 70 political drawings of Nixon, Kissinger, Agnew, and Checkers the dog—a brave and humorous condemnation of the White House during the quagmire of Vietnam. You can feel the raw frustration in his mind, as if abstraction just wasn’t getting across what he needed to say. Visiting the show at San Francisco’s Legion of Honor may make you wonder who today is drawing these pictures of W., Cheney, and crew. The timing is chilling.
