The product is a 2011 NBA Championship autographed ball featuring signatures from Dallas Mavericks players, with a focus on Dirk Nowitzki. This original basketball memorabilia piece is a unique collectible item for fans of the team and the sport. Made in the United States, this signed ball is a special memento from a historic championship season, making it a valuable addition to any sports memorabilia collection. Got this from an essay writing contest that I won when I was in 6th grade. If anyone is interested in additional provenance of the item, I have photos of me receiving the ball, as well as video of me being recognized on half-court during half time of on of their games that season.
