When it comes to game used cards, unless it is a patch, it is often hard to tell where exactly the piece came from. That is not the case with this piece, I recently landed a nice Eric Staal game used card for 2 bucks and my only reason for bidding on it was I wanted a piece of a fellow Thunder Bay boy Eric Staal. When the card arrived, I first noticed that texture was odd and very elastic. Also, the black stripe was pretty small and looking at the picture of him I couldn't see where it exactly came from.
11/12 Panini Pinnacle Threads #/50
However if you look at the jersey as a whole, I think it was part of the bottom trim.
