The pictures below shows larger side views of all (3) 1930s Cracker Jack Pop Corn Confection Tin Metal Toy Prize Whistles. These whistles have a die cut star on one side with a foil type paper inside. There were other versions with different designs made as well. These have the Cracker Jack ID number A-0031. These are stamped “JAPAN” on the sides, but the Manufacturing Company is unknown. All three of these for one price! They each measure about 1-1/2'' long. They appear to be in good to excellent used condition, except one (left one) is missing one of the tin sides as pictured.
