I'm not sure if this belongs here or before 1900. The seam does not go through the top and is a fairly rough, though straight seam. There are air bubbles in the glass, the bottom has a round or conical indentation with glass flow inside to one side, there are turning marks on the neck. The dimensions are: 10 inches high with the neck and top 3 of the 10 inches and 2 inches in diameter.
