Butter sculptures at the Iowa State Fair

The butter cow, an Iowa State Fair staple since 1911 when J.K. Daniels sculpted the first one, is located in the Agricultural Building. After sculpting her first butter cow in 1960, Norma "Duffy" Lyon sculpted all six breeds of dairy cows over the next 45 years, as well as Garth Brooks, a butter version of Grant Wood's "American Gothic", the "Peanuts" characters, Iowa native John Wayne, Elvis Presley, a Harley-Davidson motorcycle, various animals and a butter rendition of Leonardo da Vinci's "The Last Supper". Lyon was succeeded in 2006 by her longtime apprentice, Sarah Pratt.
