I purchased 2 Keen bottles from a local antique shop in Bryan, Texas. The bottles have no markings on them except for embossed “Keen” on the sides and “Keen” on the bottom. The best information I have discovered so far is that the Washington County Bottling Corporation (https://texashistory.unt.edu/ark:/67531/metapth117914/#collections) in Brenham, Texas (~40 away) bottled beverages with the same logo that is on my bottle. Then I found this identical bottle for sale on ebay (https://www.ebay.com/itm/Cedar-Grov...442695?hash=item362b955c07:g:YMgAAOSwq45afO4u) that says it was manufactured by the Keen Bottling Company in Cedar Grove, Louisiana. Does anyone know anything about these bottles? Age?
