12. Notre Dame Fighting Irish

Designer: Theodore Drake

Year Logo Introduced: 1963

$50. That's all cartoonist Theodore Drake was paid for one of the most iconic logos in American sports history. His Leprechaun, with dukes up, first appeared on a pocked schedule for Notre Dame's football team. Due to its popularity, the fighting figure quickly found form elsewhere and was featured on the cover of Time in November of 1964.
