The mark consists of an anthropomorphized bison head, body, and arms. A top hat sits on top of the bison head with its horns protruding through the brim of the top hat. Hockey gloves cover the bison's hands. The bison is holding a hockey stick. A picture of the state of Illinois sits to the left of the bison's mouth with a star pinpointing the City of Bloomington. Two concentric lines in the shape of a shield frame the bison. The lines at the bottom of the shield meet to create a circle framing the letter "B".
Color is not claimed as a feature of the mark.
