I recently purchased a 28 oz Dr. Pepper bottle, and i can't find any information on it. It still contains fluid and does not appear to have been open. the numbers on the bottom of the bottle read 70, L, 1214, 71 . It is like this one but the label is paper not foil. http://www.ebay.com/itm/Soda-Bottle-vintage-Dr-Pepper-rare-foil-label-with-original-lid-/321294219500?pt=LH_DefaultDomain_0&hash=item4acea0b8ec how old is it and what is its valule?
