Infantino/Orlando cover per Comixscene #2, although Nick Caputo notes that it is not clearly stated if Infantino penciled or only provided a cover rough for Orlando to complete. Previous indexer credited Infantino with inks. Fred Snyder and the Incomplete Bernie Wrightson checklist credited Berni Wrightson on inks, noting: "Though I can't quite see it, it certainly does not look like Infantino's work (in fact the dragon looks like it was inked by a different inker than the figures."
Letter Page in issue #4 states it is a collaboration between Joe Orlando and Carmine Infantino.
Loosely adapted from the novels A Princess of Mars and The Gods of Mars.
Adapted from the novel At the Earth's Core. Inker credit from later letter column & Greg Theakston (May 8, 2006). First Crusty Bunker job. Per Alan Weiss, "For sure the story in Weird Worlds # 2 is the first Crusty Bunker inking orgy... You can see (Frank Brunner's) inks on the Mahars. All those guys up at Continuity helping out a fellow freelancer in distress. Adams inked most of the figures. You can see a clearly Starlin figure panel 3 on page 8.Jim helped out penciling some background stuff and some background figures and I think a couple of animals. Ralph Reese spent half a night on the background in panel 4 on page 9. He also inked the sea serpent on pages 10 and 11. Wrightson inked the gorilla guys on the first two pages. The humans in the splash panel are my own inks, with Neal on the bottom panel. Page 2 has my inks on humans in panels 1,3,4, and maybe 5. Panel 2 looks like Neal on David, with me on Abner and the bearded guy (Gak?) ( how's that for slicing it about as thin as it gets?)." (May 9, 2006)
