Wonderful Vintage Modernist style Armillary sphere with chromed concentric rings arranged around a central brass sphere, mounted on a chrome tripod stand. An armillary sphere is an instrument that is traditionally used as an astronomical demonstration device or sundial. The nine rings on this one represent the orbits of the nine planets around the sun, which is represented by the brass sphere. This is an American Import from the last half of the 20th Century. Fantastic overall condition. This is large and fairly heavy at 25" high by 13" wide.
