Looks like a really cool Folk art Piece of the late century. If so to find the maker could be near impossible, I can't see to close from the pic, but if so looking close at it can tell you sometimes the ability of the artist, That is to say someone who made 100's of their craft, ( which can lead to a clue ), or someone who did a weekend project, which one would not be able to find the true maker or cir.
