This could quite possibly be the best Chicago Cubs shirt ever made. I've been looking for one for almost a year now, and I finally got one for my birthday!
Here's Hope's history lesson of the day: Wrigley Field was built in 1914. Back then it was known as Weeghman Park and the Chicago Whales played there (but, that's beside the point). From 1914 to 1988 only day games were played at The Friendly Confines (except for that one time that the All-American Girls Professional Baseball League played their all star game under temporary lights in 1943). So these shirts, created in the late 1980s were protesting the installation of stadium lights.
