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:
