Near as I can tell, Mail Pouch was a brand of the Bloch Brothers Tobacco Company, which was acquired by Helme Tobacco Company in 1983. This sign may have been maintained by Helme before they were acquired by Swisher in 1986, and operations were consolidated in Wheeling, West Virgina.
There is still tobacco being grown in Wisconsin, not much, probably less than 1,000 acres and most of it goes into smokeless products.
(This is all speculation on my part. If anyone knows the story, please share it here.)
They normally aren't in that kind of shape. Usually faded or patched over.
I have more photos to post, but I put that one up right away because I *KNEW* I'd get your attention with it!
For a long time, I knew that tobacco was a major crop in Wisconsin, but I admit, I was surprised when I drove into Edgerton. The Mail Pouch sign was one of the first things I saw.
