Butter Cow


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 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. 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.

The iconic Iowa State Fair butter cow will share her cooler with notable nighttime personalities this year. Long time Iowa State Fair butter sculptor Sarah Pratt, along with her apprentices Hannah and Grace, will be sculpting the likenesses of Iowans Johnny Carson and Steve Higgins as well as a sky glider seat to commemorate the 50th year of the Main Sky Glider. Steve Higgins is the announcer on The Tonight Show Starring Jimmy Fallon, so Jimmy Fallon will be joining the crew too.

Fallon, known for his on-air impressions, will get his own impression in butter at the 2024 Iowa State Fair. Fallon will be sculpted alongside the Tonight Show’s announcer, producer and Des Moines, Iowa, native Steve Higgins in celebration of 10 years with Jimmy Fallon as the host of the show.

Another Iowa native will also be featured in butter – longtime Tonight Show host Johnny Carson. Johnny Carson lived in Corning, Avoca and Red Oak as a child. Carson took over the Tonight Show in 1962 for a run that lasted three decades.

The butter cow, along with butter versions of Iowans Steve Higgins and Johnny Carson and Tonight Show host Jimmy Fallon, will be featured alongside an iconic sky glider chair as the main Sky Glider celebrates 50 years in 2024. All of the sculptures will be on display in the John Deere Agriculture Building 9 a.m. to 8 p.m., during the Fair, August 8-18.
