Teenage Mutant Ninja Turtles.

The Teenage Mutant Ninja Turtles comic strip was started on December 10, 1990, by Creator's Syndicate as a daily. The comic strip ceased publication in January 1997. The strip ran seven days a week, but (at least for part of its run) the Saturday strips consisted only of fan art and were not part of the storyline, which was published Monday through Friday.
