Susan Davis' design for this poster was influenced by the American Art and Crafts movement and the Art Deco movement. The Arts and Crafts movement dates circa 1910-1930. This represents a transition from Art Nouveau into Art Deco. The Art Deco movement dates circa 1925-1940. There are aspects of this poster that are both Arts and Crafts and Art Deco. However, the design and style of this poster is unique. It is the creation of a complex and talented Montana artist who spent years visiting and interacting with the park.

The poster is dated and one-of-a-kind. When it goes out of print it will become even more collectible.
