An Iowa artist is busy this summer creating special sculptures for the Iowa and Illinois state fairs.
Michelle O'Neill reports Sarah Pratt has been sculpting the butter cow for the Iowa State Fair since 2006.
Sarah Pratt says 2018 is the 100th anniversary of Deere and Company's Waterloo Boy tractor. And the Iowa State Fair asked Pratt to recreate it in butter. As a 14-year-old in 4-H, she learned how to sculpt from Norma "Duffy" Lyon," Iowa's "butter cow lady." Pratt took over in 2006 when Lyon retired.
