I found an old Dr. Pepper bottle yesterday while MDing. I'm wondering when these bottle were made and different bottle websites give different dates. Some say 1930's some say 1960's. Anyway, it says "Dr. Pepper, Good For Life" on the front and the back has the clock with the 10 2 and 4. The bottom says "Ft. Worth, TX", which is the city I found it in. Any help would be greatly appreciated. Thanks.
