Product of mammoth bones
 

Sorry for the photo quality, pre-interest, as it were, to the eye, the assessment - how such a composition might cost?
At least the price gap.
Never faced with products from mammoth bones.

Who are you to say that this photo?
At least need to know the time of creation, material, size, name, etc. .. carver
And so, on this picture, may cost one thousand dollars, maybe .....

Roger, I'm sorry, I will add photos later
