See notes to folio 78 verso of the sketchbook (D10549; Turner Bequest CXL 70a) for a run of sketches associated by Eric Shanes with Turner’s watercolour Richmond Terrace, Surrey (Walker Art Gallery, Liverpool) )1 engraved by J.T. Willmore in 1836 for Picturesque Views in England and Wales, but surely earlier and related to other Richmond subjects as well. Here, Turner concentrates mainly on the far horizon as seen from Richmond Hill, giving only brief indications of the wooded Thames valley below.
