Enamel on gold plate humpback whale tie tac or pin perfect condition ll2111

For whale watchers, biologists or just anyone who cares about whales, this tie tac or pin is black and white enamel on gold plate and is just under 2 inches across. The pin has a post and tack gripper and in is perfect condition. This would be great on your jacket or hat. I believe it is supposed to be a humpback whale but can't swear by that. I am sure it is a whale. Condition is perfect, probably never worn.
