As you may guess, King Comics featured characters published in the comics strips by King Features!
No issue 70 cover at the Grand Comics Database (for which I should thank much more often for these great cover images), so here's Issue 80!
Issue 90! I wonder if that's Jack Burnley being referred to on this cover?
Issue 110's cover is missing too, so here's issue 120!
Another five issues spelled the end of this title!
