Rare Signed Rosenthal Tapio Wirkkala Gray Cogwheel Dish from 1963. Unusual asymmetrical wavy profile in a dark blue gray glass that produces a varied and attractive specular effect. This design came in four sizes. This is the smallest. Collect them all I say.
It has a very small fleabite on the top edge rim that does not detract from the display or utility of this fine piece of collectible crystal. Made in Germany. Original foil label still intact. Acid-etched “R” logo with the Wirkkala signature below. 9 × 3 inches.
