Animals and plants go Midcentury Modern in Charley Harper's clever conservationist paintings. Inspired by backyard biodiversity and the wonders of nature preserves, Harper portrayed wildlife with heart and humor, in flat colors and simple lines. His depictions of various ecosystems and, above all, brilliant birds, showcased his trademark style of Minimal Realism. The 12 paintings here are as popular now as the day they were made, and they continue Harper's legacy as an artist whose work was a quiet catalyst for environmental action.
