For years, Woodring ran ads for "Jimland Novelties" in the back of his comics. These toys, books and oddities included a kit to make a frog's (severed) legs swim by hooking them up to a little motor, and another kit for leaving Woodring's own fingerprints around your home. For a time, Woodring was sending his readers free drawings, his "jiva portraits" of what he imagined their souls looked like. A sample of the "Jimland Novelties" pages can be glimpsed in the back of "The Book of Jim".
