In 1970, a new look to the again angry Bluejay face wearing the sweater with the letter “C” and tennis shoes.

Just two years later, returning to a version of the 1941 original logo, altering the tail feathers slightly, giving him a meaner posture, and using a smaller “C” on his sweater.

In 1955, the Bluejays tipped the scale with a much heftier weight and sported a friendly disposition as opposed to the gritted-teeth fierceness of the original.

In 1940, a journalism professor named Joseph P. Murphy — a 1938 graduate of Creighton who was now the yearbook moderator, decided it was time CU had a more lively logo. He hired an artist in Ames, Iowa, to develop a caricature of a Bluejay, and it debuted in the 1941 yearbook.

The first logo was an actual blue jay, perched atop a branch with a circle around it. Called the “Birdwatchers Bluejay” logo.
