In addition to Milwaukee artists like himself, Mitchell, Bruce Walthers, Don Glassford, and Wendel Pugh, Kitchen began to publish works by such cartoonists as Howard Cruse, Trina Robbins and S. Clay Wilson (as well as taking over the publishing duties of "Bijou Funnies" from 1970 to 1973), and he soon expanded his operations, launching Krupp Comic Works, a parent organization into which he placed ownership of Kitchen Sink Press and through which he also launched such diverse ventures as a record company and a commercial art studio.
