Vintage, Antique Bone, Hinged Folding Chess Set. I an told that this may be Aztec / African (?) But I can't confirm that. Very nice condition, although there are small bits of the board that would benefit from a small repair. See Photos. It is a really nice rare item that is certainly a talking point. 😃 It is approx 1ft X 1ft as seen in the photos. Please see my other items listed for sale.
