I believe the following books need updated labels:
The first book that I believe needs a label update is X-Men Annual #14, which hit the stores/stands May 29th, 1990. The current label that CGC assigns to this book only mentions a “Gambit cameo”, but he appears on 9 pages and 15 total panels, which for all intents and purposes, comprises a “full appearance”. Since the annual was available a full two weeks before X-Men #266 (which is currently labeled as the “first full appearance of Gambit and hit the stands on June 19th, 1990), I think the Annual should be updated and labeled as “the first full appearance of Gambit.” I believe with increased interest in Gambit due to the upcoming movie, this is a change that needs to come sooner rather than later so novice collectors can know they’re getting the real “first full appearance.” There’s a current thread in the Copper forum that provides many pieces of proof to support this label change, including shipping dates in the Spring/Summer of 1990, the copyright info for both books, and scans of the panels and dialogue that Gambit has in X-Men Annual #14. That thread is located here:

The second book that I think needs label clarification is the Walmart Exclusive Iron Man: Movie Special Issue #1 from September/October of 2008. This was an ashcan sized, squarebound comic that came with certain copies of the Iron Man movie DVD sold in Walmart stores. This comic is set in the Marvel Cinematic Universe and features Agent Phil Coulson extensively. It predates all other appearances of him in the comic medium. Scans of the book in question and Coulson himself are featured here:

CGC currently labels Battle Scars #1 (published November 2011) as the first appearance of Phil Coulson, but it’s only the first appearance of Coulson within the Marvel 616 Universe. It is predated by not only the Walmart Exclusive Iron Man: Movie Special #1 in 2008, but also the Iron Man/Incredible Hulk/Nick Fury one shot comic (set in the Cinematic Universe, published February 2009) and the Iron Man 2: Agents of S.H.I.E.L.D. one shot (set in the Cinematic Universe, published in November 2010). Pictures and scans of those books are here:

Thus, I propose some sort of labeling of these books as follows:
Walmart Exclusive Iron Man: Movie Special Issue #1(2008) - First appearance of Phil Coulson
Iron Man/Incredible Hulk/Nick Fury one shot (2009) - first appearance of Phil Coulson in a regular size comic
Battle Scars #1 (2011) – first appearance of Phil Coulson in the Marvel 616 Universe continuity
The third and final book I believe needs a label update is Avenging Spider-Man #9 (2011). This book needs to be noted as the issue where “Carol Danvers becomes Captain Marvel”. Although in continuity this issue takes place after Captain Marvel #1 (2011), Avenging Spider-Man #9 came out a week earlier, and contains a printed preface from Marvel on the first page acknowledging this fact. That page can be viewed here:

CBCS are already labeling graded copies of Avenging #9 “Carol Danvers becomes Captain Marvel (2nd in Continuity)”, and I would like to see CGC do the same before I send you guys my copies to be graded.
