I have a good friend that has a neat piece in his collection. He has had it a very long time and says it a Mayan burial statue and is quite valuable. Have you seen anything similar to this before and would have any idea if it's worth?
I certainly am NOT an expert on Central American art, but something about it just does not look Mayan to me. More Aztec, maybe.
My first thought on seeing it was "mother and child". Maybe "goddess and king or noble warrior?"
A starting point might be to take it to the history dept., of the U of T there in Knoxville.
