A stunning Claret from the turn of last century. The lid is off, however the hinge still moves and could be fixed. It is 12 tall without the lid, top neck is approx. 2", the base is 4 3/8" and the bulbous center is 6. No chips, cracks or breaks, the bottom of the glass is a bit cloudy, I was able to wipe it cleaner then it was, but did not have the tools to get in a do it completely.Weight is 2 pounds, 10 ounces.
