I recently came upon a sealed vintage bottle of Heublein Manhattan Cocktail. It is basically a very old pre-mixed Manhattan. I have no idea how old it is, and am having a lot of trouble dating it. I haven't had much luck finding any information about it. The label reads: "Heublein Manhattan Cocktail - The distilled spirits in this cocktail is blended whiskey" The bottle itself actually says (molded into the glass itself) "FEDERAL LAW FORBIDS SALE OR RE-USE OF THIS BOTTLE" It is also adorned with a couple of stamps that read "US Internal Revenue - Distilled Spirits - Tax paid" followed by some type of serial number. These stamps are over the top of the bottle, which I imagine are to form a type of legal seal, and have not been tampered with. I have just given you the most vague description of an item and am asking for much more information than can be assessed from the provided, however, is anybody aware of a source that may know more about it? I would like to assess the value of such a bottle, but am not really looking to sell (for legal and sentimental reasons). Any suggestions are greatly appreciated!
