I looked all over the net years and years ago, about 1998 - 2009, about, and I had/have thousands of wallpapers. Most of them were just grouped together by someone else and I didn't have a clue who made it or who was in the wallpaper. For all of the Calvin wallpapers, they are just match ups that had some editing done to them to make them fit more. More so on the comic side then the background. I can't draw and I'm not pretending that I can. I drew nothing.
