If you’ve somehow missed the news that this year marks the centennial anniversary of the National Park Service, don’t worry: There’s still plenty of time to celebrate. While visiting the parks is probably the ideal expression of your appreciation, this gorgeous 160-page coffee table book from Nashville-based Anderson Design Group is a pretty good substitute while you plan your next road trip.

The book features posters showcasing all 59 National Parks—from Acadia to Zion—as well as oil paintings, photos from history, and other bits of NPS miscellania. When the project started about five years ago, owner and lead artist Joel Anderson traveled to a handful of parks with son Nathan (who wrote the book) to collect seeds of information and inspiration that would kick-start the whole process. The posters in the book all share a retro vibe and a distinct kinship with promotional parks posters of days past. While a cohesive set, the works were designed by different artists within Anderson Design Group, and their distinct styles are on full display.

You can pick up 59 Illustrated National Parks: Celebrating 100 Years of Wilderness and Wonder for $49.95. Check out a few of our favorites below.
