1930-1940 Tortoise Shell Bakelite Bowling Motif Necklace

Art deco Whimsical tortoise shell bakelite (ball and pins tested by simichrome) bowling motif necklace. The center ball has three finger holes with five pins on each side. The ball is 3/4" diameter. Chain is most likely a different plastic. All original brass tone fittings. 16" length. Love this piece-its a conversation starter. Very good condition.
