I can't find examples of slabbed versions of this book, probably b/c there are only 3 graded copies in the world. A lot of the UK stuff came with gifts, and the CGC label says it came with a badged taped to the front. It looks attached, so I wouldn't mess with it. Even if the tape was a defect (in this case I don't think it is), it would be a zero sum game to remove it b/c you'd likely create a tape pull/leave behind residue in the process. It also looks like some The other UK gifts (like a mask & boomerang with Captain Britain 1 & 2 respectively) if they aren't there, get a qualified labels. To me, this is a 7.0/7.5 as-is b/c of the big corner bend. That might be pressable, but having the badge attached will make that harder (impossible?). Depending on what the badge is made of, a good presser might have a technique to work around the badge. I know they make little card frames so they can press things with inserts without pressing the shape of the insert into the entire book. I'm going to tag @joeypost for comment, b/c I could be talking out of my backside on this.
If that's foxing on the white text and whatnot, I lower my initial offered grade by 1.0
