If I had an SS book I wanted to read (I know. Just suspend your disbelief for a moment, okay.) I would have it cracked out by a CGC employee at the booth such as; Gemma, Bill (when he was there) or Joe. I would have to read the book at the booth and then resubmit it for Signature Series grading. It would still retain the yellow label. Not the best of scenarios convenience wise, but it does provide the opportunity to read, feel or smell a book that most believe to be forever off limits.
Are you laughing while typing this Watson ? Who's really gonna do this Possible, yes. Ridiculous, very.
