Hello, all. Total noob submitter so please forgive me for any egregious mistakes. Here is another book from the 30 that I'm submitting. My biggest reason to get my books graded is so that one day, it'll be easier for my son to sell. With that said, this book is signed by John Byrne, Terry Austin, and Chris Claremont - all non-CGC witnessed since it was signed at a Lone Star Comics event long ago. Since it's not on the cover, should I even bother submitting it? If I do, what's the grade? Thank you all for your help!
