In Chapter 8, More Harvey of Jack Kirby’s Austere Inking I briefly examined “This World Is Ours” from Alarming Tales #3. Some have suggested Steve Ditko as the inker but when I wrote that chapter I had not seen any Ditko inking from that period. Well Dave Sim reviews some Ditko comics from this period and links to images are included. If this material is any indication it looks like Ditko was inking mainly with a pen and it does not look like what is done in “This World Is Ours”. So as far as I am concerned this story was inked solely by Jack Kirby.
