The Passport To Your National Parks® program, launched in 1986, provides information and encourages visitation to all of America’s national park service units. It includes a passport book that lists all national parks in the United States and U.S. territories, and provides space for ‘cancellation’ stamps which can be found in almost every national park in the system. The program also encompasses several other supporting publications, such as the Kids’ Passport To Your National Parks Companion® and the Passport to Your National Parks Explorer Edition®, which is a larger, more-detailed version of the original passport book.
The 2.5" x 2" sticker sets are designed to be placed in your Passport to Your National Parks book. The 2 part set can also be used for scrapbooking and affixing to any other momento of your trip to either Wind Cave National Park or Jewel Cave National Monument. One sticker has a photo of the cave, the other sticker has a short description of the park and the package back provides more detailed information. There is also a geographic sticker set for Wind Cave.
New for 2016! The Passport Collector's Book - larger than the original passport book, this wire bound book features a hard cover and information on nearly 400 park sites. It is a good mix between the original passport book and the Explorer Edition.
