The 572 is probibly one of the more stylish and streamlined
models that was ever offered by Grunow. I aquired this set at the
2004 ARCI "Radiofest" which was held in Elgin, Illinois.

The Grunow 572 dial consists of two layers. The top portion
consists of a clear celluloid layer with the dial scales printed on it.
The bottom portion is made of glass with a Green and White background
printed on it. Illumination is accomplished with two dial lights mounted
on opposite sides of the dial, and when lit, the dial gives off a soft
white illumanicance similar to that of a fluorescent lighted clock.
