Iowa is Famous for Having the World Record for This Biggest Thing Every state in America is known for having at least one thing that is bigger than anyone else. In Iowa, it has to do with a man's face and it's true we do own the world record and I can prove it. I want to be clear that this was not my idea. Blame Zippia. If you're not familiar with them, they are a career/jobs website. Zippia shared a helpful map showing what each state is known for having the biggest thing of. I don't know any other way to explain it.
