I was really disappointed when I went the NLCS game 1 and saw that there was no Cubs scorecard. MLB takes over for the NLCS and the World Series. So that left me with just the NLDS card to find. It was a fairly simple find.
It looks like the picture is from September 16, the day after the Cubs clinched the division title. The clinched because of a Cardinal loss the night before, so they didn't have a chance to celebrate. The celebration was going to be after this game on the 16th and the won the game as Miguel Montero hit a walk off homer.
