Garth!
Cartoon Garth is the stand-in for the somewhat older, hairier, blinder, and not-so-cartoon Garth Haslam... a.k.a. "the guy drawing the stuff."
I first drew myself this way sometime in the 1980's. Following good old comic-book logic, I've generously allowed Cartoon Garth to remain about the same age through the years so he will look pretty much the same in new things I draw as in older things, making him more recognizably a repeating character.
I often make him the butt of jokes. That may not say good things about me.
