This 12-inch plate is a rare find from E I Dupont DE Nemours made of high-quality pewter. The most likely brand is Kirk Stiff Pewter but I see no marks. It has been beautifully engraved with the DuPont Logo. The plate was made in the United States and falls under the category of collectibles and metalware. It is a great addition to any collection and is sure to be a conversation starter. The plate is in rough shape but ready to be displayed. Scrapes and dents are visible.
