Ranger Naturalist Service
From The Giant: The Definitive Obey Giant Site
Ranger Naturalist Service is a Work Progress Administration, or WPA poster from the 1930's depicting Old Faithful erupting at Yellowstone National Park.
This particular poster, among other fantastic examples of American propoganda artwork that originated under the WPA, is noteworthy as it served as the stylistic inspiration for the 2005 Shepard Fairey work entitled Greetings from Iraq.
