I have no idea what it's worth, but since it is unmarked, and has a fairly clean bottom (highly glossed look and free of debris), it appears to be something commercially made, like Pier One or similar. The images look very "familiar" to me and I can't place it. I haven't been collecting for very long however, so I would defer to someone else for a more professional opinion.
well it is not nippon. and not moriage. the whole drawings are not right. I am thinking some quick tourist thing to sell in side makets somewhere maybe at the New Jersey shore.
