For Trade: 1957 Topps Unitas PSA 6 for ?
 

I have a couple of Unitas RCs and would like to move one for another card or set or something interesting. Cash going either direction is fine too. I have a PSA 6 and a nice PSA 7 OC. Things I'd be interested in:

Wayne Gretzky RC
Ernie Banks RC
Walter Payton RC
Joe Montana RC
Lebron Topps RC
Graded Jackie Robinson cards
86-87 Fleer Basketball Set

If you've got something in this vein, reach out to me. Thanks.
