Amazing three-ball set which salutes the 2001 World Series Championships of the Arizona Diamondbacks.First ball salutes the Arizona Diamondbacks as the 2001 National League Pennant winners. Second ball salutes the Arizona Diamondbacks as the 2001 World Series winners and has the scores from each game against the New York Yankees. Third ball salutes the two teams in the 2001 World Series -- Diamondbacks vs. Yankees. Brand new and still in the original packing and box and never opened nor displayed. Very historic.
