Rare 60s/70s Vintage GM promotional Barware Set 1912, 1953, 1958, 1962, 1967  For Sale

I found this set sealed in a basement at an estate sale. I have the original box which is a little crushed on one side. See the picture. What I found was a decanter and barware set. The decanter shows a 1912 Chevrolet, which was the first year of that style car I believe, it has a 1953 Corvette, which I know is the first year of that car, then a 1958 Impala, which was also the first year, a 1962 Chevy two nova, and a 1967 Chevy Camaro. I believe this may have been a salesman’s bonus set for good sales or selling a particular option or it may have been a promo directly to the dealer GM. The gentleman’s estate his wife told us he was in the car business. The set is in excellent condition except there is a chip on the corner of the Chevy two glass. Please see the picture for more detail. As I pulled the staple and broke the original tape on this box, I can only assume that that glass was put in this box chipped to begin with. One very rare collectible. Never seen another nor have I seen any for sale. Chance to own an excellent piece of automotive history. Please check my other listings for more deals and thanks for looking.
