In my search for all five of the Five Flavor version of this label, I found a sixth flavor. I was hoping to find the Ginger Ale in a Six Flavors version, but this is what I found. Were White Rocks found in a wind tunnel? It would make sense that they screwed up and made this can, but pulled it before market and sold them to a wind tunnel. It has all of the earmarks of one.

Definitely wind tunnel. Ginger ale was produced, even though it was not listed. Here is the book info.

Dug the Ginger Ale. The ones I have in the collection are from Denver CO.
