DC Comics has announced that it will publish a hardcover edition of a 1978 Superboy and the Legion of Super-Heroes story at the original tabloid size.
The Legion of Super-Heroes is a 30th-century superhero team whom Superboy visits from the present (1978). When he arrives to attend the wedding of Lightning Lad and Saturn Girl, two of the Legionnaires, he immediately realizes that something has gone awry: Everything in the future world is different from his previous visits, and he suspects someone is meddling with the time-stream. Nobody else notices the difference (of course) but when the bride and groom are kidnapped, Superboy rounds up a group of Legionnaires and brings them back in time to 1978 to try to get the timeline back on track.
Like the original, the reprint includes an eight-page section with information about the members of the Legion, written by Levitz with pencils by James Sherman and inks by Jack Abel and a two-page pinup of the members by Mike Grell.
DC has a lot of material originally released in this format in its vaults, but most of it has not been reprinted at this size. DC did release a hardcover edition of its Superman vs. Wonder Woman Collector's Edition last year (see "'Superman vs. Wonder Woman' Hardcover").
