Articulated Fish Bottle Opener

1960s, made in Mexico by Los Castillo (sticker still on the tail fin), this is an articulated piece made from abalone shell, with a bottle opener mouth. Please note the few missing pieces around the tail fin/ near the tail end of the fish on both sides, it does not affect the overall beauty of the piece nor the function.
