JMW Turner ‘Three Seascapes’ 1827 One of a group of cursory marine sketches datable to the late 1820s. The canvas bears three sketches of sea and sky, one of which was painted upside down so that one sky serves for two subjects if the canvas is turned. It is exhibited with two seascapes the right way up.
