Antique plate. I think the condition is good, but about half of the underside has a string-like discoloration for some reason. (Crackle??) I don't know the details, so I'm not sure. You can also see four indentations where it was stacked and fired (I don't know how to describe these either). If you understand antiques and like them, please consider purchasing. I have another one of the same item, but the underside has more discoloration, so I'm listing this one first. If you are interested, please leave a comment.
