The National Gallery of Art, and its attached Sculpture Garden, is a national art museum in Washington, D.C., located on the National Mall, between 3rd and 9th Streets, at Constitution Avenue NW. Open to the public and free of charge, the museum was privately established in 1937 for the American people by a joint resolution of the United States Congress. Andrew W. Mellon donated a substantial art collection and funds for construction. The core collection includes major works of art donated by Paul Mellon, Ailsa Mellon Bruce, Lessing J. Rosenwald, Samuel Henry Kress, Rush Harrison Kress, Peter Arrell Browne Widener, Joseph E. Widener, and Chester Dale. The Gallery’s collection of paintings, drawings, prints, photographs, sculptures, medals, and decorative arts traces the development of Western Art from the Middle Ages to the present, including the only painting by Leonardo da Vinci in the Americas and the largest mobile created by Alexander Calder. This famous American art museum features two online exhibits through Google. The first is an exhibit of American fashion from 1740 to 1895, including many renderings of clothes from the colonial and Revolutionary eras. The second is a collection of works from Dutch Baroque painter Johannes Vermeer.
