These were published by Topps Comics in the early 1990s (each issue came bagged with a trading card). I believe I have all of the individual regular-comic format issues, but they were also reprinted in trade paperback format as the Ray Bradbury Chronicles (not sure of the publisher, but it wasn't Topps). How many volumes of the trade paperbacks were issued? There were also limited-edition hardcovers of these books, which I believe ran even longer than the trade paperback volumes. How many hardcover volumes were there? I assume there must have been new stories not included in the original run of the comic-format series, so which volumes had previously-unpublished stories? Some of the stories were reprinted from the earlier EC Comics adaptations, but were any of the EC Bradbury stories not collected in these volumes? I have the two mass-market paperbacks of EC Bradbury reprints issued by Ballantine Books in the 1960s. Any help is appreciated.
