With the sketchbook turned horizontally, Turner filled this page with studies of boats and figures working around them, presumably taken in the Loire Valley. Turner subsequently used local rivercraft to enliven his views of the Loire which he worked up for printed reproduction in The Keepsake annual (1831) and Turner’s Annual Tour: Wanderings by the Loire and Seine (1833–5; later reissued as Rivers of France).1 For examples, see Tate impressions T05107 and T04689.
