This is a rare, authentic, double dot, full Pepsi bottle from the 1940's. It is NOT a reproduction. It still produces bubbles when shook. As far as I can tell, it has not been opened but, I am not 100% that it is the original cap. It does have expected age wear. There are scratches on the paint, on the bottle, and the cap. There are two wear rings on the bottle that go completely around the bottle (see pics). It is a 12 oz. bottle. It was bottled in Mason City, Iowa. Replicas of this style of Pepsi bottle is the exact one used in the first Back to the Future movie. These replicas can also be found in the wild but again, this bottle is one of the originals from the 40's.. Thanks for looking!
