This was the first work of art commissioned for Rockefeller Center and ultimately set the stage for its renowned Art Deco style. The three limestone panels are allegories of time and evoke radio’s vast reach and never-ending transmission—an appropriate theme, since RCA was the first tenant in the building. At that time radio was just a recent development in America, and the Rockefellers, recognizing its worldwide importance, wanted to highlight its advent with these three bas-reliefs. Today these panels serve as celebrated Art Deco architectural embellishments.
