The Passport to your National Parks is a small, 6" x 3" travelogue that lets visitors to National Parks record where they've been, insert specially made stickers, and learn about the many National Parks in the United States. There is a much larger one called the Passport Explorer Edition that is larger, weather proof and comes with more pages.
