Today, the United States is home to 59 national parks, designated protected areas for the enjoyment of the general public or the preservation of wildlife. The U.S. Congress is responsible for establishing National Parks, the first being Yellowstone in 1872.

In the mid-1930, at the height of the Great Depression, the Works Progress Administration and its Federal Arts Project was tasked with designing a series of inspirational posters to promote the landscapes and wildlife of America’s parks. Here is just a handful from the collection stored at the Library of Congress to celebrate 100 years since the National Park Service (NPS) was founded.
