Antique Nelson McCoy barrel mug. c:1920's. Being sold as a collectible display item only; I did not manufacture it so I don't know what is was made with; it might not be safe for food use. Early yellow ware mug. Thick, heavy and shown in the book. It looks like it has an incised #4 inside a shield inside a circle on the bottom. No chips or cracks. It is 4.75 tall.
