Amazing Heroes previewed the mini-series in 1983 with this terrific Kane cover. Kane always did a great job with sword & sorcery. The story by Jan Strnad put Ray Palmer's marriage to Jean Loring in turmoil and sent the hero into a microverse populated by barbarians.
The first mini-series sent die-hard silver age Atom fans into a tizzy. I remember reading this and thinking, but yeah, where's the JLA? Of course, that was the whole point, to reinvent the Atom and send him off into another world.
Reading this stuff all over again, it was clear that Gil Kane loved this story and did some very inspired work. After the first mini-series finished, there were 3 more specials that were published in 1984/85/86. This splash page was from the 1984 special, where Ray Palmer reflects on his feelings between the Jean and barbarian babe Laethwen. If only the Atom could know of Jean's future actions in Identity Crisis...he would have stayed in that microverse forever. Nuff Said!
