After guiding The World’s Greatest Heroes in their adventures for nearly a decade, writer Gardner Fox and artist Mike Sekowsky were moving on—meaning some big changes were in the air, leaving new writer Dennis O’Neil and new artist Dick Dillin to take charge of the World’s Greatest Heroes! The first work of this new creative team is seen in JUSTICE LEAGUE ARCHIVES Volume 8, a 240-page hardcover reprinting JUSTICE LEAGUE OF AMERICA 61-66, and 68-70 (plus the cover to 67, which was a reprint from 1967-68), which showcases this transition of creative teams. This archive also features the art of Sid Greene, George Roussos, Neal Adams, and more, as well as a cover by Sekowsky and Jerry Ordway. Featured in this volume are: another annual team-up of the JLA/JSA (in which they face the treacherous T. O. Morrow) that also introduces the mysterious Red Tornado; the cosmic challenge of the Chaos Maker; a tale guest-starring The Creeper and Mind-Grabber Kid; the return of the crafty criminal The Key; and an adventure in which the members of the JLA go head-to-head with their own individual foes! Plus, how can a small-time dictator challenge the JLA? And is Green Arrow really a murderer? All this and more can be found in this volume featuring a new introduction by O'Neil, plus a cover by Sekowsky, newly inked by Jerry Ordway!
