1965 Coca cola prototype of an all plastic foldable 16oz 6pk bottle carrier with test market photos

This is a collection all found in a Dow Company folder. The items listed were in the folder. Item 1:an all plastic 16oz 6pk coca cola bottle carrier that folds. Items 2:3 different photos measuring 7in×5in. There are 2 copies of each photo with 1 copy out of each set having a stamp on the back reading "please credit this photograph to The Dow Chemical Company". Each photo has a piece of paper taped to the bottom describing the different stages of the market testing of this all plastic foldable carrier being conducted in each photo. Contains info on each persons name and who they are and the names and locations of the businesses each photo was taken. All 3 of the paper descriptions are dated 11/8/65. Item 3: is a larger photo measuring 10in×8in. It does not have a 2nd copy but is the copy with the dow stamp on back. From the remnants of old scotch tape on back of this photo is evidence its missing its paper description. Item 4: is the folder itself. The front of the folder has the printed logo for the Dow Chemical Company accompanied with an image of a 6pk bottle carrier labeled "beverage". All the items are part of coca colas market testing for the carrier made from The Dow Chemical Companys plastic material being able to mirror the same foldable abilities as the cardboard 6pk bottle carriers. In the descriptions of its photo result of its test tells how an all plastic carrier has more durability and brings more customer appeal compared to its cardboard counterpart. Another photos description shows and tells how its image takes place at the case loading station inside in the Augusta Georgia Coca Cola Bottling Plant showcasing how the all plastic foldable carriers capabilities easily allow it to be interchangeable in the product lines of the existing cardboard carriers. This prototype coca cola carrier is without a doubt 100% authentic easily proven with its photographic proof and info. Now with that considered and the results of my research this prototype carrier seems to be the only 1 in existence. Having that kind of rarity in the world of collecting coca cola memorabilia given that my item and with its pieces in the collection as a whole should give it a level of value and interest as a ultra rare item from the history of America's most recognized company. But Im sure collectors dont acknowledge items that coke never put into production as anything other than junk or useless unpractical products that couldn't meet the standards or innovations that the coca cola brand demands.
