Herky the Hawk
Herky the Hawk is the athletics mascot of the University of Iowa Hawkeyes. Herky is a student dressed in black and gold, including wings made out of fabric, with a headpiece shaped like a hawk's head. Herky was first drawn as a cartoon in 1948, and was first portrayed at a football game in 1959. Periodically, Herky's wardrobe and overall design have been updated. There are currently two different styles of Herky costumes. The version used at football games and related events features Herky wearing a Hawkeye football helmet. The version used at basketball games and other events features Herky with different facial features and no helmet.
