A Mail Pouch Barn is a barn with one or more sides painted with the slogan:
TREAT YOURSELF TO THE BEST
Starting in 1890 the Bloch Brothers Tobacco Company of Wheeling West Virginia began offering farmers a bit of cash and a years supply of their Mail Pouch chewing tobacco in exchange for painting at least one side of their barn with their slogan. Even without the cash or product, a free coat of paint helps keep your barn siding protected, and this deal would look inviting.
The advertising campaign continued until the mid 1990’s. Over 20,000 barns in 22 Midwest and Southeastern states were painted during that 100+ year run. If you have any of these in your area or when you spot one while traveling, take a look. They won’t be around forever, and are an interesting slice of American rural history.
