Today I've got the Scorecard Extra programs that the Cubs debuted in 2001. It was a monthly mini-program that has the official scorecard stapled inside. It's follow-up, Gameday, lasted through the 2018 season.
I know that Scorecard Extra started in 2001. It was sold until 2010, 2011, or 2012. I can't pin down the date because I've never seen one from 2011 and 2012. I have copies of its replacement, called Gameday, starting with 2013. But I not seen anything called Gameday for 2011 or 2012 either. I won't get an answer until I see something show up on Ebay from 2011 and 2012.
The Scorecard Extras were typically 16 pages long with the scorecard in the middle. The Gameday versions were much bigger, with an average of 50 pages. It's almost like they went back to a regular gameday program.
I decided that I wasn't going to go after all six from each season. Instead, I have just one per season. As stated above, I'm missing just the two from 2011 and 2012.
