Usually Im on the side of not cutting up things to seperate the autograph, but recently I purchased a J Roy Stockton signed copy of "The Gashouse Gang and a couple of other guys". The book is heavily damaged, mainly water damage and animal (likely a dog) chewing damage. The inscribed and signed page is in good condition but faded some likely due to the water damage (ghost image of the writing is on the opposite page) but still strong.
In this case would it be better to remove the signed page from the book or is it still more valuable left as is even though the book is in horrible condition?
