Believe it or not, I recently duplicated marvel chipping. I was using a simple paper cutter to cut a 40 page legal sized document to standard 8.5X11 size. The paper cutter had a dull blade and the document wound up with what looked exactly like marvel chipping. The only problem with this is that this chipping went through the entire 40 pages. As far as I know, Marvel chipping only affects the cover. The question is, were the covers cut seperately and then later on added to the pulp pages? Anyone know?
