IMO the color breaking spine stress areas are a little too extensive for me to put it in the 7's. Comics in this grade range are the most difficult to grade. The rest of the book is absolutely beautiful and it presents very well! If I were grading it to sell it I would give it a 6.5, but because it presents so well I would not be surprised if it came back CGC 7.0. If you are sending it in, please let us know how it turns out. Thanks for sharing!
P.S.
I always remove any tape, old or new completely from the bag and either throw it away or stick temporally somewhere far away from the comic before I remove from its bag. (its happened to me too)
