I got this signed in person back when Winslow was a Brown. No COA, but I do have a picture of him signing for me. Looking to either sell, or trade for other signed memorabilia- Olympic stuff is a plus, but is not required. If you are interested, please let me know, and let me know what stuff you have for trade. I am not looking for cards, or card cash, just signed memorabilia, or cash/paypal
