I'm trying to collect all the backs up to Carolina Brights (which I just got 

), anything more scarce is out of my budget.  The last semi-rare I need is the aforementioned AB 350 no frame.  Front of the card is inconsequential, just looking for a decent presenting back.  Let me know what you got, thanks!
