A Vintage Decorative etched Colored Enamel Brass Metal Ware Tankard with Glass Bottom

A decorative etched enamel on brass beer tankard with a glass bottom. This tankard has age appropriate wear and patina. I do note the bottom rim has a uneven circle so it may have been made this way of perhaps toasting over the years has cause this issue. . Measuring about 5 inches tall by 3 inches across the top and 4 1/2 inches across the bottom. Simply wonderful !
