The Rogers State University campus is known for its large-scale sculptures of three U.S. presidents Thomas Jefferson, George Washington, and Abraham Lincoln created by sculptor Yon Sim Pak. Born in Korea, Pak built a reputation as a portrait painter, and came to the U.S. as a young adult. Each statue is constructed with skeletal structures of steel, covered with a white masonry cement and polished with a special polymer to give them the look and feel of granite. Pak used a special blend of cement, which was patented by his friend Paul Kellert of Mannford, Okla.
