Dr Pepper 10 Ounce Bottle 10 2 4

The infamous 10 2 4 Dr Pepper bottle. In the long ago Dr Pepper passed itself off as health food as the body needed a jolt of sugar now and then. Now and then would be at 10am, 2pm an 4pm. Actually it doesn't seem all that unreasonable. Get a jolt of caffeine every few hours. It is just a 10 oz bottle. You may note the 10 2 4 are arranged as they would be on a clock.
Note sure when this bottle was made. Had to be some time before the 12 oz bottle was standardized. Also 10 2 4 was over by the 1970s
Sorry the photos are not the best. Trying out a new background.
