How does CGC treat signatures on the inside of the book?

Hi there, first time posting a question here, so I hopefully I do it right, but... If I submit a Cerebus #1 (of which many copies are signed) How is this treated? I believe I have seen blue label copies of this book that say it has been signed, but I might have been dreaming. Thanks in advance for the info.

It would either read: Name written on # page or "Stan Lee" written on # page (if the signature was legible) but it would not say Signed by if a witness were not present at the time of the signing.
