From the day the doors swung open in 1923 to the park's renovation in the mid-1970's, this letter "I" played its part in spelling the name of the most famous sporting venue on earth. Black paint has weathered and chipped in places to reveal the blue oxidized copper underneath. One end of the letter is a bit mangled, but that's part of the charm. A thrilling, fascinating piece of the game's most sacred ground.
