was curious is harveys silver age comics...bee man,jack frost,pirhana etc public domain? what about archie comics the fly? also curious about magic man,nemesis? not sure who published those. also why no kid montana from charlton?
While the copyright owners of Harvey, Archie and American Comics Group (Nemesis, Magic Man) were lax about renewing the copyrights of many of their comics of the 1940s and 50s they were not quite so negligent about renewals of their 1960s material. Since we can only host public domain material those titles that were renewed can not be hosted here.
As to Charlton's Kid Montana (some nice Pete Morisi art in some of those), the simple answer is that no one has yet uploaded any issues. I'm kinda' surprised as the title had a good healthy run of 42 issues and there are plenty of them that we could host.
Keep checking in though as new stuff turns up all the time and that could very well include issues of the Kid.
