Artist Dennis Simms Fossilized Walrus Tusk Bolo Tie

ONE OF A KIND piece from artist Dennis Simms, signed. Good preowned condition with some discoloration of the silver end pieces and one small flaw to the metal. Please check photos. Made from fossilized walrus ivory. Leather cord. The hardware at the back turns; I believe this is the design (?) but not entirely sure so wanted to mention. It is secured onto the ivory and then the clasp piece turns a bit to each side. Length of leather cord approximately 36” Pendant measures approximately 2x1”
