Cool photo. I wish there were more like it. But I imagine most of those old bottling plants are long gone by now, or have been changed over to something else like the one in Corbin, Kentucky. I had to look on a map to see where Corbin was. I noticed a lot of Daniel Boone related stuff in the area.
I noticed the 7up symbol on the building had seven bubbles, and thought the snippet below from a Bill Lockhart article might be of interest. I'm sure it would be easy enough to determine when the building began and ended as a 7up bottler, but the dates below may shed a little light on the logo itself.

"During 1938, someone noticed that eight bubbles did not match well with Seven-up. As a result, the labels from 1938 on contained seven bubbles."
P.S. I wonder who that "someone" was? A 7up employee, or a soda bottle collector? Lol []
