1991 was just the second year baseball's All-Star Game was played in Canada (Montreal hosted the first, nine years earlier), and appropriately enough, the winning and losing pitchers - Jimmy Key and Dennis Martinez, respectively - represented the two teams up north. This official 1991 All-Star Game baseball was signed by 30 greats, including: Tony Gwynn, Ozzie Smith, Andre Dawson, Eddie Murray, Barry Larkin, Craig Biggio, Will Clark, Ryne Sandberg, Paul O'Neill, Tom Glavine and John Kruk. The ball is practically MT though some of the signatures show evidence of fading.
