My favorite typing champion has long been Albert Tangora. Why? There's just something about his handsome face and smile that I find — well — winning.
Notice how Tangora's championship Underwood has a special extended lever instead of the traditional stubby one, for easy returns, and a huge, distinctive bell that he could hear over the din of a typing competition.
I even sneaked Tangora into my 2010 NaNoWriMo novel:
I recently found this pamphlet attributed to Tangora, published by Royal in 1939. It includes 50 tips, an illustration of Tangora at a Royal, and more propaganda for the latest Royal typewriter. You can download a PDF of this charming bit of ephemera (about 7MB) by clicking on its image.
You can see Tangora in action here.
