Your bottle is a known type and is considered to be rare. If you look in the COKE BOTTLE CHCKLIST book by Bill Porter it is listed on page 33 of the FIFTH EDITION. The error is only found in the 1915 issue.I found this 1915 Coke on a construction site in downtown Pueblo a couple years ago. So far I haven't been able to find another like it and was wondering if anyone had. I can't imagine it's the only one in existence. It's embossed "PUEBLO" on the bottom, I've seen others with "PUEBLO COLO" but never one without the state....
Back then, companies weren't using two letter abbreviations for states yet. It wasn't standardized until much later.Wow! Very nice looking
I guess it's a ferly rare bottle.In my opinion the name PUEBLO was changed to for example PUEBLO COLO (or other) in order to accurate. Then no one else embossed that old name.
As long I know that bottle was designed in Nov 1915 and began to be made in 1917.
