The Yellowstone National Park poster was produced for the Ranger Naturalist Service, a department of the United States National Park Service. The original poster was created in 1938 as part of the Works Project Administration, or WPA. This poster has been faithfully reproduced by a team of artists. Working from an original poster, every detail was reproduced to create the highest quality poster available. Heavy stock paper was used to produce a non-reflective matte finish for a look and feel of the original silk screened version. The poster is in a quarter sawn white oak frame made of hand selected wood by our friends at Dard Hunter Studios.
