The picture below shows three larger views around this 1930s CrackerJack Pop Corn Confection LithographedTin Siren Whistle Toy Prize. It has a young boy and two young girls dancing or walking outside holding hands. There are also butterflies, flowers and a dog as well. The siren whistle is simply marked “JAPAN”. This whistle was made with many variations of images which many were used as prizes by CrackerJack. Inside there is a metal wheel that spins fast and makes a siren noise when blowing in one end of the tube or barrel. The whistle measures about 5/8'' x 1-1/4''. The whistle works and it appears to be in excellent condition as pictured.
