Lee Lawrie's carved rendering of Wisdom is above the east entrance of the main building and is flanked by his renderings of Sound on the left and Light on the right. The Wisdom frieze above the entrance is accompanied by an inscription that reads: "Wisdom and Knowledge shall be the stability of thy times," from Isaiah 33:6 (KJV). Lawrie's three renderings are complemented by two limestone bas-reliefs by Leo Friedlander: one of Production on the north elevation, and one of Radio on the south elevation.
