AJ0605 Posted May 11, 2019 Share Posted May 11, 2019 I feel like I see this kind of crease on many silver age books. I don’t see it as much on Bronze Age and newer? What’s causes it? It’s less of a crunch and more just a uniform colorbreaking line. It seems to always be in the top left. Link to comment Share on other sites More sharing options...
flashlites Posted May 12, 2019 Share Posted May 12, 2019 This is caused by the cover overlapping the pages. Over time and handling the cover is sort of pressed down , more of a bend than a crease. It shows up even more on the reading edges in my experience. Link to comment Share on other sites More sharing options...
