Irwin was frequently complimented in print by a Alex Toth who also illustrated some Fox stories for Red Circle Comics back in the '80's (you can see one here).
Fortunately the goofy costume with the shirt shelves sticking out morphed into a more traditional crime-fighting costume over the course of the strip. As it stands, this story has a nice Bob Burden feel about it - one would almost expect The Flaming Carrot to show up!
