Here is the reply from Harry on this bottle plus there could actually be 5 more bottles floating around.

"I had to call Bill and Kim on this one as I don’t remember anything like this.

So the story is, that about 15 years ago a guy met up with Bill during the Atlanta Trade show. He worked for a novelty bottling plant and had a six pack of cola bottles mocked up with the design you have. Bill can’t remember if all six were all different designs. What they wanted to do was market the colas using the Harbour Lights brand in stores like Bevmo and gift stores on and around the coast. Nothing ever came of that first conversation and I assume the idea was dropped by the bottling company.

This sure is an unusual find".

I will have some pictures posted later on.
