Soldiers Tin Shaving Mug

This is a soldiers shaving mug. If they were lucky enough to have one. They would fill it with water, and have a piece of soap, like shown in picture, in the other section of the mug. They would lather up their face, but dipping the lather brush into the water side, then into the soap side, to make a soapy lather. Then as they shaved, they would rinse of the razor in the water side. My wife found this for me in Franklin Tenn. what a great find.
