I bought these from a walk-in at the Perkiomenville show on Saturday. I was lucky enough to be at my car while he was getting out of his. I've shown them dirty, clean, and a closeup of my favorites. None are marked, the pink/purple ones are nice (one has a chip on one ring), the gingerale one is fizzy, and the blue one (not sure if you would call it cobalt or not) is gorgeous and fizzy (a few small nicks on it). I think this is my favorite purchase of the show.
