A simple two tiered design makes up Wrigley's architecture. The broadcast booth seems to hang precariously behind homeplate. During the 7th inning stretch, all eyes would look towards the booth for guidance as the late Harry Carey sang Take Me Out to the Ballgame. That second tier was actually added, 12 years after the ballpark opened. Wrigley Field debuted with only a bottom deck, and stayed that way till 1926.
