I cannot find anything remotely resembling this piece unless I look at prehistoric African art it's an African man in a boat and on the bottom of the boat is a swiveling fish
There are no markings on this at all from what I can tell. I know nothing about antiques and can't find anything like this on the net. The ones that are similar are painted. I don't know if this lost its paint or not, but I think it looks nice just the way it is.
