Do you have one in your home? Do you have a door that will swing shut if it isn’t held open with a doorstopper? We used to have a cast iron iron.
I saw a window full of vintage door stoppers, mostly painted cast iron. There are animals, people, flowers. Gnomes. Right now I use a concrete (or is it cement?) owl. I bought the owl in a gallery in Mansfield Ohio.
People collect them. Vintage and Antique Doorstoppers or door porters as they are called are written up in Collectors weekly
