Man, nice analysis! Thank you!
I figured this was restored, since this book unrestored and raw even back when I bought it (2002) would still have had a price tag I wouldn't have forgotten. LOL
The front cover absolutely needs a press. I'll have CCS screen it, but I doubt they can remove all the stuff you outlined. I'm still gonna slab it, though. Gotta provide full disclosure for the eventual buyer.
For some reason I bought 3 X-Men 1's back then... this one , the one in the PGM forum which is deteriorating as we speak (!), and an CGC 8.5 (R) book, which sadly was trimmed. Should have spent more on some AF15's instead, maybe... but I ain't complainin'.
