I honestly do not know how many issues the wonderful magazine Back Issue sells when it is published every other month, but it is almost certainly less than it deserves. I know of no other magazine that every issues gives as much great content focused on interesting books and tidbits of comics history.
The magazine focuses on the comics of the seventies and eighties, the comics that a good chunk of modern comic readers grew up either hearing about or actually reading. (A little bit of both in my case, as I started regularly buying non-G.I.Joe & Transformers comics in late 1988.) Like most comic readers of the time, I marveled at the rich histories of the big two universes while still being curious about all these other books I always heard about but never saw on the newsstand. Like any good comic fan, I have since sought out many of the most famous stories of that era, but even that can only brush the surface of the many great titles published during that period.
Enter Back Issue. Every issue of Back Issue is filled with insightful stories about stories from those years, from the biggest characters to the most obscure titles imaginable.
