Blake’s image was printed onto smooth white paper. The light pencil crosses are framing marks of unknown date; they could be Blake’s. The inscription near the lower edge appears to be in Blake’s hand, perhaps written at the time of production. The writing at lower right, intended to be hidden by any frame, has been added by several curators. Blake’s hand-finishing extended beyond the colour printing at each corner, and has been extended by others, for neat framing within a window mount.
