Porcellino began drawing and self-publishing his autobiographical zine King-Cat Comics and Stories in 1989. It is one of the longest-running minicomics produced today. His work has been translated into German, French, Swedish, Spanish, Italian, Dutch, and Korean, inspiring several generations of cartoonists worldwide. Starting in 1992, Porcellino has also run the Spit and a Half Comics Distro, an international distribution resource for self-published and small press art and literary comics. He lives in Beloit.
