Rogue First Appearance: Avengers Annual #10 and How to Identify It

Rogue first appeared in Avengers Annual #10 (cover date 1981), published by Marvel, by Chris Claremont, Michael Golden. The source puts it this way: "Rogue's first published appearance was in Avengers Annual #10 (1981).".

• Interior story role (villain, not hero, on debut): as she flees at the end of the story, there is no suggestion of redemption in her future — her first impression is that of a powerful enemy.
• Debut team affiliation: she debuts as a member of Mystique's Brotherhood of Evil Mutants.

• 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.
