"Cheesehead" can refer to:
The original display of a "cheesehead" hat was at a Milwaukee Brewers vs. Chicago White Sox game in 1987 when the Brewers started the season 13-0. It was handmade out of foam, painted yellow. Ralph Bruno, the creator of the original hat, then made popular by center-fielder Rick Manning, who saw the hat while playing. Bruno then had the idea of starting a business to sell them as novelties. The "Cheesehead" trademark is owned by Foamation, Inc. of St. Francis, Wisconsin, which began manufacture of the wearable, foam cheesehead in 1987. The company also offers a plethora of other foam products, such as: different types of hats, neck ties, pins, keychains, magnets, cup-holders, coasters, and footballs. Cheeseheads have become more commonly associated with Green Bay Packers fans (and Wisconsites in general) since mass production of the original hat began.
