The restaurant Kentucky Fried Chicken was started by Colonial Sanders in 1951.  I am uncertain who designed the logo but it seems it has always had the face of the Colonial in it.  The logo has undergone some changes since the company was started in 1951 but has still remained recognizable.  The logo that is in use now was created in 2007 by a branding agency called Tesser. The font in to logo has changed a few times and the title of the establishment was shorted to KFC so that the word "fried" would no longer be in the logo. I remember being surprised when the logo was changed to a more simple vector illustration after being used to the 1997 logo for so long.
