Trying to dig up backstory for you gentlecreatures!
Mail Pouch Tobacco was a product of Bloch Brothers, founded in 1879. On top of a few rather ... unusual... ads like this, they had a big campaign of ads on barn sides, starting in 1891. They would offer farmers a few dollars a year, plus a free repainting of their barn, in exchange for a big ad on the side. They painted over 20,000 barns in this manner. There are sites dedicated to cataloging them.
Here are some photos. Some of the barn ads are preserved for historical reasons and you can occasionally spot one in some rural areas of the US.

That 40 yo baby though 😅, you'd think they'd got out of fashion in the late 1800
