Help with Ivory Carving

[PlaneGypsy]

I would appreciate any help understanding this item I found in some boxes I purchased at an auction. It appears to be an old ivory carving. I believe their are two signatures shown along with the separate Japanese writing? I have tried to show the detail in the piece and hope someone knows more.

Thank you in advance.
