Hi guys, below is a link to a local auction house.  There are a few  cards, some autographs and memorabilia.  
Is there any chance that the  Mantle and Mathewson cards are real?   I don't do cards so I am just curious.   If by some crazy chance they are, you might get a good deal.  
I have no  affiliation with the auction house and am not promoting this in anyway.
