Seller: blubetterjay (1,103) 100%, Location: Framingham, Massachusetts, Ships to: US, Item: 332037414331 I think it might be Chinese because the shape reminds me of Chinese frog pots, but I have no definite information about it. It certainly is not Pre Columbian. It seems to have a splash of ink or paint on it, visible in the first picture, as if it was meant to signify something. No cracks, and nothing I'd call a chip, but it is a primitive piece with variations common to such things. It also has some mineral deposits on it.
