Finberg listed this as one of 22 leaves from this sketchbook found ‘in a parcel labelled by Mr. Ruskin – “M. 16. Leaves of S. 229. Laid down.” They have been mounted on cartridge by Mr. Ruskin.’ Evidently, Ruskin isolated these drawings because they were pencil outlines, without the additions of chalk or gouache found elsewhere in the sketchbook.
