I acquired these from a man a few years ago who told me these came out his dads restaurant in Chicago. If you look at the last photo this was how these were mounted to the table for the menu and then an area for salt and pepper ketchup etc. Pretty cool pieces. They almost look like they are porcelain over steel??  Measurements are in the listing photos. Pictures are the main part of the description. Please ask any questions Before Purchasing. Thank you for looking at my listing.
