An interesting take on the newspaper comic strip super-hero, using a version of the Justice League (which is Batman-less in this particular story). I think this was one of the last mass market-sized reprint paperbacks. before full-sized trade reprinting became the norm.
Naturally, there’s 1-2 panels to a page, instead of a single strip on each. So the art is a bit disjointed. Still, it’s fairly good art by comic book veterans George Tuska and Vinnie Colletta. Martin Pasko’s story is okay, but Aquaman gets the short shrift in this run (and he knows it). Considering the differences between comic strips and comic books, the sequence is much better than one would think, using Vandal Savage as the main villain.
Worth a read if you’re a Superman or a JL fan. Beware: It’ll probably take most people about five minutes to read it all.
