It's graded at 9.2 with white pages, unpressed. There's some contention about the status of this one. I bought this book raw over 15 years ago from someone who didn't even know what it was. I submitted it to CGC a number of years back, and it came back as a 9.2 with a blue label (number 0006154007). I cracked it to have Stan Lee sign it a couple of years ago, and had CBCS do on-site grading.
It came back the same 9.2 with the validated signature, but they put a "restored" label on it. It's talking about black ink in the grader's notes. I think what likely happened is Stan's pen hit part of the comic near the spine, because there's been no restoration attempt made on it.
