Iowa State Fair Butter Cow

Butter Cow

The world-famous Butter Cow is located in the Agriculture Building. In 2006, Sarah Pratt of West Des Moines became the Fair's fifth butter sculptor.

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. Lyon passed away in June of 2011.

In 2006, after 15 years of apprenticing with Duffy, Sarah Pratt of West Des Moines 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.

While a real dairy cow weighs more than 1,000 pounds, a 600-lb. butter cow would butter 19,200 slices of toast and take an average person two lifetimes to consume. Much of the butter is recycled and reused for up to 10 years.

In addition to the Butter Cow, a companion sculpture also graces the Agriculture Building coolers. During the 2015 Fair, a celebration of the 80th anniversary of beloved family board game, Monopoly, was on display. Following are some that have been on display in previous years:
