I like the 9-11 card. I'd never thought about creating some for special occasions. You could get a special background for the first game in the new stadium.
I have 2003 WS game 4. It was supposed to be Clemens last game. It still isn't complete as I never did fill in Alex Gonzalez's 12th inning walk-off HR. It still shows a 3-2 count after 7 pitches.
