This is the larger variant of the 3342 art glass bowl by Tapio Wirkkala. 
The decorative lines and a fantastic shape are key features also of this creation by Wirkkala. It was made at Iittala glass factory in the 1950s.
The about 70 years old bowl has some surface scratches of normal usage, mainly on the inside of the bowl. These are notable on close inspection but the overall impression of the bowl is good and it has no chips nor flea bites.
