Damaged Henry William Stiegel Tankard

First time I've shown this piece. I wish it was in better shape of course. I bought it years ago from someone who had bought it at an antique store some decades before me. A friend who is well known in collecting early European glass (we will keep him anonymous) helped me identify the piece and said, "You have just bought your first piece of REAL glass. Now, save up the money to buy one without cracks in it..."
