Bruno, who could not be reached for additional comment, used a knife to cut a wedge of foam and burned holes into the material to make it look like Swiss cheese in creating the original hat. He then painted the foam yellow to look like cheddar cheese.
Now, let's be clear, cheddar cheese does not have holes. And Swiss cheese is not orange. But the creative liberties taken by Bruno paid off. The original hat's public debut by the creator was at a Milwaukee Brewers professional baseball game, but the Cheesehead has become synonymous with Packers football.
"The popular Cheesehead hats have come to represent Packers fans all over the world and we're excited to officially welcome this special brand to the Packers organization," Gabrielle Dow, Packers vice president of marketing and fan engagement, said in a statement. "We're looking forward to building upon the legacy the Bruno family has created over the years and offering our fans even more Cheesehead items to love."
The Cheesehead hat for adults currently sells for $24.99 on the Packers' website, with a child-sized hat priced at $19.99.
Foamation has branched out over the years to produce novelty hats for other professional sports teams, including the Pittsburgh Steelers, according to a past interview with HuffPost. That hat featured a steel beam stuck through a steelworker's hat. There have also been copycats for other teams made by other companies, including the Bonehead in Cleveland, a PU dog bone shaped hat that has room to hold beers when turned upside down.
Other Foamation products have included firefighter, police and cowboy hats. And there's even been a fedora made from the company's signature PU.
