It started out as a sketch of a man with an unruly dog and a shopping bag (Or is that a man-purse?). The Bad curve replaced the dog as an inspiration from my "bad curve" question. I don't like the bag. Maybe I'll either give him some drawing implements or a poop-and-scoop doo-dad.
In case anyone asks, the font I used is Isoctuer, which I can't find out anything about, but I think came with AutoCAD. The rest in the suit are single stroke fonts.
