This black-and-white line drawing depicts a highly decorative skeleton key, featuring a large, scrolled bow with hatching for depth, a tapered shaft with vertical striations, and a geometric bit with cutouts. The collar includes stacked conical elements, evoking Victorian-era metalwork. The style suggests an engraving from a 19th-century catalog or technical manual.
