Trio of single signed 2001 World Series first pitch baseballs with the American flag which was specially produced to honor the victims of the September 11 tragedy. All three (Jeter, O'Neill and Rivera) have signed the sweet spot in black pen, with each rating a 9/10 overall. The baseballs are in Near Mint to Mint condition. These autographed 9/11 baseballs are tough to find.
