I've just been perusing my Sotheby's Concise Encyclopedia of Glass, ('91) looking for something else, when I found what I am pretty sure is this, illustrated on p. 172.
It's called "Bolgeblick" with two dots above the o, designed by Aino Mariso-Aalto, 1932.
There is a note under the caption which reads;
"This range of pressed glass, designed in 1932 by the architect wife of Alvar Aalto, was made until 1956 by Karhula. Recently, some pieces have been produced again.
I'm not getting very far with a search on the name though, in finding your dish.
