A poster touting Montana created by Martin Weitzman in the 1930s for the Works Progress Administration's (WPA) Federal Arts Project. In those days tourism augmented natural resource extraction as an economic driver; today it is an industry with huge environmental and social impacts all its own. Image courtesy Library of Congress
