I've seen photos and descriptions of this bottle; clear glass with a large print font letter for each white diamond; D A N A. The bottle says "Quality Beverage" and "Coca Cola Bottling Works of Cincinnati, Ohio." This indicates to me that it was a franchise bottler (but I don't have a time frame). They had the 7-ounce (7 5/8 inches tall) and a 12-ounce bottle (9 1/2 inches tall). Perhaps you can find out more by contacting the historical society in Cincy -- if they have one -- or the city's library system.
