Unsure of origins, bronze or copper over wood.  Is Very unique and very old! I couldn't find anything even close to being similar with many online searches  I believe the iron oxide spots are where the clad layer is attached.  Clothes and hat are  clad  in bronze and trimmed in a black grout. Not your average African art you find on eBay and the price reflects it, but I believe this is a true relic and important piece of history. If my price is way off and you have any info on the origins,tribe,style of construction, etc. ,

it would be appreciated..
