Rare, authentic 1947 Captain Midnight Decoder Whistle

This is the coolest piece of 1940s memorabilia.My mom had this when she was a little kid growing up in a different era. This is an authentic 1947 Captain Midnight Decoder Whistle. It's in rough condition, but not bad for being 62 years old!!!! It still works, as far as I can tell, the whistle gets my dog to perk up her ears -- though I've no clue how a decoder works :-) Take advantage of this great opportunity to own a rare piece of history.
