According to Cook and Wedderburn (XXI.278 n. 1), the drawing was removed from the Teaching Collection by Ruskin in 1887. It has not been traced, and is represented here by the engraved reproduction by J.C. Armytage included in the Library Edition.
Presumably presented by John Ruskin to the Ruskin Drawing School (University of Oxford); first recorded in the Ruskin Drawing School in 1878; removed from the Drawing School by Ruskin, 1887.
