Have a question. I have a few purchased items which have been signed but not witnessed. If I would submit them to CGC they would not be eligible for the Signature Series to my understanding. Is this correct? I have a copy of Vengeance of Bane signed with letter of authenticity, but this also would not be eligible for Signature as well, I am assuming.
Side note on this subject, I saw an item on eBay graded a 9.8 but flagged for having a marker stain on cover. Marker stain was Stan Lee signature. Maybe I am answering my own question. No witness no Signature
