This American art deco radio was designed by Walter Dorwin Teague (1883 – 1960 ) for the Sparks – Worthington Company, Jackson Michigan and introduced in September 1935 for the 1936 model year, it was produced until 1940. The radio, known as the "Bluebird"; is model number 566 and is considered an icon to deco collectors. A 14" circle of mirrored cobalt blue glass intersected by chrome circles and three "speed" lines is centered with an illuminated tuning dial. The mirror rests on the two ebonized ball feet and hides the radio works. The radio is in excellent condition.
