Sparty is the mascot of Michigan State University. Sparty is usually depicted as a muscular male Spartan warrior/athlete dressed in stylized Greek costume. After changing the team name from "Aggies" to "Spartans" in 1925, various incarnations of a Spartan warrior with a prominent chin appeared at university events and in university literature. In 1943, MSU art professor Leonard D. Jungwirth designed a statue for the university, which had to be cast in terra cotta because of World War II rationing. In 2005, the university replaced Jungwirth's original statue with a bronze replica, moving the original indoors to protect it from the elements.
Sparty appears in several other incarnations. In printed literature, the university uses a copyrighted cartoon Spartan, usually drawn with a grimace and several days worth of whiskers, lending the nickname of "Gruff" Sparty. Finally, Sparty appears as a foam rubber mascot with an oversized head. The mascot costume, worn by an anonymous student, appears at most university sporting, alumni, and fundraising events; he is often portrayed in MSU notices and materials.
