The crown jewel of the Iowa State Fair will not be making an appearance this year. 81-year-old Norma Lyon passed last month. Her claim to fame was not cherry pies, or steer judging, or quilting. It was butter sculpture. (Yes, you heard me.)
Norma crafted hundreds of pounds of butter into animals, famous people (notably a bust of Barack Obama during his presidential campaign), and cartoon characters. Her greatest achievement was a life-size butter diorama of the "Last Supper" in 1999, consuming a whole ton of butter.
While this is a distinctly rural art form, it's art nonetheless. You're welcome to argue with me, but the medium is less important than the subject/execution. At least, I think so.
