ALOU

Chicago Cubs blog Bleed Cubbie Blue (a truly great site) brings us this very strange picture from yesterday's Mets/Cubs game. The name "ALOU" hanging outside of the Mets press box.

A cruel joke? A sign he's on the path back to Shea? A tribute to Steve Bartman?

I have no idea. This is just strange. According to BCB, they took the sign down before the game started. Thoughts?
