The woman singing the national anthem in this photo is Karla Kaufman.
Or, at least, that was her name then. I was sent this photo by her now-husband, who was wondering exactly when this photo was taken. Neither of them can remember the exact date.
So I had a look, and I also sent it to Mike Bojanowski.
There are a number of players — as well as a coach and manager — 100 percent identifiable in this photo. The key is that Jim Essian is in this photo, and that definitively dates it to 1991, since that was the only year Essian was in uniform for the Cubs as manager.
