A poster for the United States National Park Service, showing a deer drinking from a stream in the forest. This was one of more than 200,000 works created as part of the Federal Art Project, which was the visual arts arm of the Great Depression-era New Deal WPA Federal One program. FAP artists created posters, murals and paintings; some of which stand among the most significant pieces of public art in the country.Poster credit: Frank S. Nicholson
