The picture below shows larger front and back views of the (2) Old Cracker Jack Pop Corn Confection Tin Metal Toy Prize Mouth Flute Whistles in this lot. These whistles are not dated but they are believed to be from the 1930s. One is colored gold and one is colored silver. The silver one is stamped “JAPAN” and there are no markings on the other one. We do not have the Cracker Jack ID number for these and the manufacturer is unknown. To judge the sizes, the larger of the two mouth flute whistles measures about 1-3/8'' x 1-3/16'' x 3/8''. They appear to be in good condition as pictured.
