The picture below shows a larger view of this Old CrackerJack Pop Corn Confection Tin ToySpinner Whistle Prize. The spinner whistle is not dated but it is believed to be from the 1920s or 1930s. The string may have been replaced and not near as old. The string goes on both sides of the spinner and when it is wound up and pulled it will spin very fast and whistles as it does. The maker is unknown. To judge the sizes the tin metal whistle section measures about 2-15/16'' x 1-3/16'' x 3/8''. It works well and appears to be in good used condition as pictured.
