Take to the air with hawks, falcons, and other winged creatures in Charley Harper’s Hawk Mountain Sanctuary. In the 1970s and ’80s, Harper created this and nine other posters for the National Park Service, designs that gently persuade viewers to honor the natural world. Brett Harper wrote of his father: “I think he hoped that his art might nudge viewers to reflect and decide for themselves about issues such as biodiversity, sprawl, habitat loss, insecticide poisoning, climate change . . . and so on. Charley simply wanted human beings and animals to coexist.” With each of this circular puzzle’s 500 pieces, share Harper’s faith in his art as a quiet agent of change. For Ages 10 and up.
