Ricky Williams Autographed Official NFL Football (TSC) This is a great gift item for any true football fan. This Official NFL "Game Ball" is signed by the one of the greatest running backs of all time! Signed boldly for your enjoyment, these balls carry a Certificate of Authenticity from Total Sports Concepts (TSC), who because of their certification process has become one of the most respected sources for autographed memorabilia in the industry. TSC has many athletes under exclusive contract, among them, Donovan McNabb, Tim Couch, and Ricky Williams. As you can see in the picture, each ball comes with the COA attached. The COA is similar to a credit card and contains a picture of the actual autograph on the item, a picture of the athlete signing the item, and a serial # for the item which can be registered with TSC for verification. Since you would have to pay anywhere from $65 to $75 for just the ball by itself, this is truly a great item at an unbelievable price!
