Butter Cow History

In 1911, J.K. Daniels sculpted the Fair's first butter cow and was succeeded by J.E. Wallace of Florida. In 1957, Earl Frank Dutt of Illinois took over the sculpting duties. Norma “Duffy” Lyon of Toledo, Iowa, began sculpting in 1960, becoming the fourth person and first woman to sculpt the Fair's butter beauties.

In 2006, after 15 years of apprenticing with Duffy, Sarah Pratt of Cumming became the Fair's fifth butter sculptor. In addition to her first Butter Cow, Pratt also crafted Superman of Superman Returns (Norwalk, Iowa, native Brandon Routh, who starred as the Man of Steel) and "Mr. State Fair" Bill Riley (in honor of his 60th Fair).

The Butter Cow starts with a wood, metal, wire and steel mesh frame and about 600 lbs. of low moisture, pure cream Iowa butter. Once inside the 40-degree cooler, layers of butter are applied until a life-size butter cow emerges - measuring about 5-1/2-ft high and 8-ft long. Each year, much of the butter is recycled and can be reused for up to 10 years.

A real dairy cow weighs more than 1,000 pounds, but the butter version comes in at around 600 pounds. Did you know the butter cow would butter about 19,200 slices of toast and take an average person two lifetimes to consume?

In addition to the Butter Cow, a companion sculpture also graces the Agriculture Building coolers.
