I am in the works for doing a signing with Jeremy Lin through Steiner so you will get all necessary paperwork and holograms from steiner with the ball so you know its real. Taking orders for autographed basketballs right now. Signing will be in a couple of weeks but I need to know how much product to buy to be signed. I will be selling autographed basketballs for $175 dlvd. Even if you are wanting to buy these to flip them you should easily be able to make a lot of money on them at this price. Please pm me if interested and we will work out the details
