Documentation/logo.txt

-This is the full-colour version of the currently unofficial Linux logo
-("currently unofficial" just means that there has been no paperwork and
-that I have not really announced it yet).  It was created by Larry Ewing,
-and is freely usable as long as you acknowledge Larry as the original
-artist. 
-
-Note that there are black-and-white versions of this available that
-scale down to smaller sizes and are better for letterheads or whatever
-you want to use it for: for the full range of logos take a look at
-Larry's web-page:

+Tux is taking a three month sabbatical to work as a barber, so Tuz is
+standing in.  He's taken pains to ensure you'll hardly notice.
