This curious antique door knocker, depicting a woman with a massive tongue, is up for auction on eBay. From the listing:
A door knocker in the shape of an ill woman’s face. Her tongue is the knocker. Marked manufacture, nineteenth century, made of spelter or some other non-magnetic base metal, I bought this in England. The manufacturer’s stamp is on the underside of the tongue: “R.E.&S.” inside a shield. The piece measures 5.125″ long and 2.25″ wide. Good working condition.
