Charley Harper (American, 1922–2007) Woodland Wonders, 1977 A walk in the woods is expertly conceived in Harper’s Woodland Wonders. This image was created for the Cincinnati Nature Center and was his first poster design of over 50 that he would create for nature- and conservation-oriented organizations. As is often the case with Harper’s work, there are critters here that you might not see until you’re well into putting this 1,000-piece puzzle together—like that bullfrog, for instance.
