This is a set of 12 different posters that make up the mural project of black and white landscape photograph posters by Ansel Adams for The Mural Project 1941-1942 paper size is 22" x 28" Image size 18" x 15 1/2" Ansel Easton Adams (February 20, 1902 – April 22, 1984) was an American landscape photographer and environmentalist known for his black-and-white images of the American West. He helped found Group f/64, an association of photographers advocating "pure" photography, which favored sharp focus and the use of the full tonal range of a photograph. He and Fred Archer developed an exacting system of image-making called the Zone System, a method of achieving a desired final print through a deeply technical understanding of how tonal range is recorded and developed during exposure, negative development, and printing. The resulting clarity and depth of such images characterized his photography. In 1941, the National Park Service commissioned noted photographer Ansel Adams to create a photo mural for the Department of the Interior Building in Washington, DC. The theme was to be nature as exemplified and protected in the U.S. National Parks. The mural project was halted because of World War II and never resumed. However, the photographs remained. Much later, in 1962, the photographs were accessioned into the holdings of the Still Picture Branch at the National Archives and Records Administration. The original prints created for the project now reside within the series 79-AA: Ansel Adams Photographs of National Parks and Monuments, 1941 - 1942, while the negatives were originally retained by Adams at the time.
