GNU's Not Unix

Does anyone know where this seemingly old image about GNU+Linux depicting Tux and Gnu come from? This page on gnu.org about a confirmedly free variant has the author mention it as an image perse "downloaded from the net years ago".

It has always been this way. Right now, I want to update a few Guix packages, but I have no clue on how to do the same. Where's the issues supposed to be created? What about creating new commit? Who is the maintainer I'm supposed to be speaking with?

Forty years ago, Richard Stallman announced the plan to develop the GNU operating system, which would be entirely composed of free software. The existence of a free operating system would enable people to operate their computers in freedom, throwing off the power of the developers of nonfree software. The GNU Project has also built the global free software movement.
