Drawn with the sketchbook inverted. The model’s foot continues over the stub of the next leaf of the sketchbook, demonstrating that the leaf was removed by Turner himself before making this drawing, and then on what is now folio 44 (D07918). On the verso of 44 is a very faint pencil outline of the same torso.
Noting the apparent intimacy of this study, Bailey wonders if this is ‘Sarah [Danby] posing for William [Turner]’. But see Introduction to the sketchbook.
