Unusual antler & exotic wood bowl. Artisan, vintage



A really unusual, signed artisan bowl that I believe is turned from antler, with an exotic wood base.  The bowl has two natural holes across from each other, part of the original structure of the material, which you can see in the second photo.  It is clearly signed but I don't know who the turner was.  I'd love to know if anyone recognizes the mark.

7/8 inch (2.2 cm) in diameter and 3/4 inch (1.9 cm) tall.
