The Horse Show Fountain in Scoville Park in Oak Park, Illinois, sometimes called the Wright-Bock Fountain, is generally believed to be a product of Bock, but the actual attribution is a bit fuzzy. Donald P. Hallmark, a Bock historian, stated the fountain was designed by Bock between 1907 and 1908 but with the help of famous architect Frank Lloyd Wright. It was Bock himself who suggested that it was Wright who pushed for the central opening in the fountain, and thus he "began to lay claim to the whole project." The Frank Lloyd Wright Foundation claims the work as a Wright design from 1903. The Frank Lloyd Wright Preservation Trust lists Wright as the architect and Bock as the sculptor.
