John Coiner / Deneen Studios marked on the bottom. Do you have a renaissance festival coming up? Then you might just need this tankard! It's large, very large. Or maybe you need a coffee as big as your head? It would work for that too. Black and blue in color. Great design. No chipping or cracks. Wonderful used condition. 6" tall by about 5" at the widest part at the bottom. That doesn't include the extra width that the handle would add. Could be a great flower vase as well.
