Fraternities Page from the 1925 Jayhawker Featuring a Bulldog.
The Jayhawk was not always KU's lone mascot. KU's first mascot was the Bulldog. For a while, the Jayhawk and the Bulldog were used as the mascot, at the same time. In November of 1958, the Jayhawk became KU's official, and lone, mascot.
