Passport Book

Passport To Your National Parks will help you discover the beauty and history found in America’s National Parks. You’ll gain greater appreciation of the National Park System in America. And you’ll have fun doing it. Whenever you visit a national park, be sure to get your Passport canceled. These rubber stamp ink markings record the name of the park and the date you visited. The cancellations are free but you have to go to the parks to get them.
