Arrangement in Grey and Black No.1, famous under its colloquial name Whistler's Mother, is a painting in oils on canvas created by the American-born painter James McNeill Whistler in 1871. The painting is 56.81 by 63.94 inches (144.3 cm × 162.4 cm), displayed in a frame of Whistler's own design. It is exhibited in and held by the Musée d'Orsay in Paris, having been bought by the French state in 1891. It is one of the most famous works by an American artist outside the United States. It has been variously described as an American icon[2] and a Victorian Mona Lisa.[3]
