Bicentennial Shaving Mug

Went riding around today with the wife and daughter for my birthday. We stopped in an antique shop along the highway, and I asked if they had any shaving stuff. They had a bunch of safety razors and a few mugs. This particular one caught my eye. I'm guessing it was made in 1976 for the bicentennial.

Anyway, for 6 bucks, it didn't break the bank to buy it, and now I have something to keep my other birthday presents company (a new badger brush and some TOBS shaving cream)
