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 shows various houses among trees, probably around Petersham and seen from somewhere on Nightingale Lane. For another drawing of a house among trees nearby see folio 76 verso (D10545; Turner Bequest CXL 68a).
There are splashes of oil or varnish on this leaf.
