Curious audience members who look up upon entering Carnegie Hall's famed Isaac Stern Auditorium will be rewarded with an intricate ceiling decoration, famously known as the "circle of lights." Beautiful as it is functional, this main portion of the ceiling—83 feet from the Parquet floor—acts, in part, as a sound reflector to the upper floors, with intentionally sparse detail to help achieve an even balance. 

This stylish bookmark is adorned with an image of this intricate ceiling decoration.
