The Little Brown Jug is an early version of a thermos. The jug is tin skin over stoneware liner, a metal stopper with a rubber gasket and a metal cap that acts a drinking cup. The jug label declares that it “keeps foods or liquids hot or cold. Butter, milk, water, coffee, lemonade, set.” It was manufactured by the T. T. Macomb Manufacturing Co., Macomb, Illinois. Jugs like these were used when camping or taking refreshment to the harvesters in the fields.
