Tape is a sticky subject! Best not to attempt removing it yourself. Very tough to make a call on this one! Grading it as is I will take a stab at it and say it may be in the 4.0 range. You have to take into account how well the book looks otherwise, maybe 6-7.0 without the tears and tape. But these defects are very significant and normally found in the 2.0 range or lower, so I split the difference and am guessing 4.0. I would love to hear from some other Boardies and see what they might have to say about it, especially when it comes to getting it restored and slabbed with a purple label. I will take a pass on commenting on that question.
