CD 133.1 Patent Dec. 19, 1871 with an enormous bubble that dominates one side. There are also tons of smaller bubbles in the dome that kind of swirl around the pinhole. The big bubble, which is completely sealed, is more shallow/flat on the left side, so the edge of it is not quite as defined. These 133.1's seldom have any kind of notable character, and I have never seen another that comes close to this one.

The condition is very good overall, though there are some annealing issues that I wouldn't necessarily define as damage, but certainly worth mentioning. The dome has a lot of tiny little annealing lines that are super shallow and hardly noticable. The base and inside of the skirt have a lot of more dramatic annealing lines where it appears the glass actually separated while cooling. None of these are fractures or anything that could worsen over time. There are also a few scattered bb dings and nicks, and the surface of the embossing has some roughness. Very unique piece! Asking $225 plus shipping.
