Actually, they are all copies. But that's a good point about the versions that are reprints of reprints. The suppliers like Rick's, Classic, etc. are all getting them from some publisher. What we need to do is compare the publishers that are reprinting them. So, to get that started, my 68 AIM is from Millenium Industries and it has worked fine for me. There is a "disclaimer" in the front that states the light pages in their version were light in the original. All the pages in UPC 6 are of good quality as Big Iron states above.
