"Postseason baseball gives us a chance to look back at some of the most memorable moments in October," Horn said. "We've got a few items that really relate to the New York Mets' success over the years. For us to be able to show these items and connect with some of the storylines that fans may see in the 2015 postseason, this is something we really draw back to history. And this is something we do at Cooperstown each day."
