I have seen these around and I think they are beautiful. The bad thing is, it is not an original. In fact, it isn't even an authentic Coca-Cola picture or reproduction. This fantasy sign came out in the 1970's and sold for $2. Although the author of the book considers it worthless, it is still a nice piece of art. Framed and put in a recreation room or something like that would be a nice addition of nostalgic artwork.
Sorry for the bad news. This one took a while to find. I couldn't find anything else produced for Coke in 1911. That made it hard to trace. Also note you can sometimes find these being sold on the internet. I saw some selling for $10 each.
