On August 25, the National Park Service celebrates its centennial. While you should totally go visit a national park, you could also ring in the occasion with another favorite pastime: coloring.
Tennessee-based studio Anderson Design Group has spent six years creating posters for each of the 59 state parks, in the vintage style of the Works Progress Administration. Now, they're available in coloring book form.
The coloring book, printed on perforated gallery-grade paper also includes five popular indigenous animals.
