Darkseid First Appearance: Superman's Pal, Jimmy Olsen #134 and How to Identify It

Darkseid first appeared in Superman's Pal, Jimmy Olsen #134 (cover date December 2, 1970), published by DC, by Jack Kirby, Vince Colletta. The source puts it this way: "First Appearance: SUPERMAN'S PAL JIMMY OLSEN #134 (1970)".

• Cameo only — face on a TV monitor, last page: readers only get a peek at Darkseid in a single panel — his big debut is just a talking head on a TV set, giving commands to one of his minions.
• Cover art by a different artist than the interior story: the story was written by Jack Kirby, with interior art by Jack Kirby and Vince Colletta, while the cover was drawn by Neal Adams.

• Indicia: the small print on the first page or inside cover gives the issue number, date and publisher; reprints usually say so there.
• Cover price and barcode: a price or barcode format that did not exist in the year printed means a later edition.
• Paper and staples: decades-old newsprint is tan at the edges; bright white pages on an old date are a warning sign.
• Restoration: color touch, trimmed edges and married covers are common on expensive keys; a grading service can detect them.

Shoot the front cover flat, straight on, in even light, then the indicia page and the back cover. Include the top edge and staples in one frame. The app reads the title, issue number and cover and matches it against the checks above; the indicia photo settles most reprint questions.
