Bucky Badger Button, Vintage 1950's
This could be 40's, they still made this kind of Tin Lithograph, fold over button in the 1950's, but I never saw any more after that.
Never used, bright and shiny (a little too shiny to make a good photo), the button is 1" in diameter, not counting the fold over tab. The price is for one, but I have 2 of them if you are interested.
Great University of Wisconsin memorabilia.
