Ok, going off on a tangent: I've only ever heard/ seen of the FLASHBACKS indirectly. Were they at all authorized, or were they bootleg? They were B&W reprints with color covers, correct?
Alan Light (founder of what is now CBG) published the reprints through his DynaPubs arm. As for being authorized, I am not sure (although I think they were not readily frowned upon if at all), but a good number of them were published. I do not have an index of them handy at the moment. Light's Flashbacks were B&W with color covers. Issues included Pep Comics, All-Select Comics, All-Star Comics, Police Comics, All-American Comics, Flash Comics, Marvel Mystery Comics, and other publishers.
However, Light's FLASHBACKS were not the only publisher offering such reprints.
A Texas based publisher also reprinted Police Comics, All-Star Comics and other titles. I have a copy of Police Comics #1 sitting right in front of me from that particular line. I am not sure if the publisher was Yesterday's Comics (Carrollton, TX) or Nostalgia, Inc. (Dallas, TX)...but I think it was the publishing arm of a big Texas based comics dealer.
There were also other lines of reprint mags (Captain George's Whizbang) putting out reprint stories and such long before AC Comics started up.
Many of these mags were affordable at one time, but now they can be most pricey to get a hold of (Ken Pierce Book, Passiac Comics [assuming I spelled it correctly] were two big suppliers of these types of mags)...fortunately, now that we have GA-UK, all but the DC/AA & Timely books are pretty much onsite.
I would wager that Jim (JVJ) remembers more about these ongoings though. That is a big hint to Jim that I would love to see his recollections of Golden Age Comics fandom from the 1970s and beyond if he will offer them.
