I have a silver-age Cap America 100 that seems trimmed/cut on the right edge; running from the lower corner to the upper...6 7/8 inches to 6 11/16 inches. So I began measuring other Silver age books and found DC's measured 7 inches just a bit wider than Marvel Silver age books. Then I went on to measure bronze issues: DC's = 6 5/8 inches & Marvel's = 6 3/4 to 6 7/8 inches. And I notice some of my bronze marvels are cut uneven between 3/16 and 1/8 inches off on the right opening side.
Are there parameters that comic sizes fall into? What are they? or Where can they be found?
Thanks!
Dan
