This is an 1845 copy of the probable original on sale at Boris Wilnitsky who want 25 euros for use of the image free of their watermark (forgetting that they get free advertising). Boris Wilnitsky’s notes for the probable original propose that "Grassi himself produced preliminary outlines, yet instructed his 18-yearl-old pupil (Döll) to finalize the paintings."
