Antique Mary Quite Contrary Cast Iron Doorstop, Littco. This doorstop was an estate sale find and is in amazing condition given its age. It still has the diamond Littco sticker, which in most cases will disintegrate or lose its adhesion and fall off after many years. Mary was well taken care of! She is an ideal piece for the avid collector, with what appears to be all of her original paint. View pictures for details.
