The Bulls alternate logo is simply removing the wordmark "CHICAGO BULLS" for the primary logo. This strong presence of a logo and without the wordmark is a classic. The "Windy City" logo is a little corny.

The Bulls also have an alternate logo during the early 70s, featuring the same Bulls logo in black with red highlights, but with a cloud that says “Windy City” below the bull’s nose on a red matted background.
