Circa 1910, The Johnson Layne Coffee Company in Saint Louis, MO was in business for only a few short years, but their flagship brand was the Log Cabin Brand of Coffee. This particular general merchandise storage bin was designed for customers to scoop out their coffee in bulk when buying the product. I am guessing the Gunpowder brand was a high potency coffee given the name, as I have seen this on a few other manufacturers tins also.
