The collection is particularly focused on portrayals of the Old West by Frederic Remington and Charles M. Russell, artworks depicting nineteenth-century exploration and settlement of the North American continent, and masterworks that are emblematic of major turning points in American art history. The "full spectrum" of American photography is documented by 45,000 exhibition-quality prints, dating from the earliest years of the medium to the present. A rotating selection of works from the permanent collection is on view year-round during regular museum hours, and several thousand of these works can be studied online using the "Collection" tab on the ACMAA's official website. Museum admission for all exhibits, including special exhibits, is free.
