Abstract: A method of using signage on a horned bovine while the bovine is engaged in a display activity is disclosed. The method can include disposing a sleeve on a horn of the bovine, the sleeve having an image disposed on an exterior surface of the sleeve that conveys information to a viewer, and causing the bovine to engage in the display activity. The sleeve can include a tube having a first end with a first diameter and a second end with a second diameter, the first end and the second end being open to allow a tip of a bovine horn to pass through. The tube can fit over at least a portion of the horn and can include an elastic material to cause the tube to contract about the portion of the horn. The tube can be a continuous tubular surface or a sheet formable into the tube.
