I would in no way apply tape to the book unless u are a conservation expert. I get that collectors have problems with restoration, but there is a true difference between restoration and conservation IMHO. I agree with jollycomics, contact CGC, explain the situation, If you are holding on to the book, and not selling, I would have conservation done by a pro, but that is only my opinion. Maybe CGC would consider a re holder type arrangement and include the pieces you have?? Either way, u do have a beautiful 1.0 there.
