I have a couple of items that I want authenticated and one of them is a dual signed Dimaggio and Williams 8x10. I t was professionally framed and matted years ago but they will only authenticate it unframed. In your opinions I have had this looked at by some of you and most opinions were that it was legit so should I tear it out of the frame to get it authenticated or leave as is and sell as is ?

here is the item # 221169283669 it is going to expire in 22 minutes just curious if anyone thinks it could possibly be real
