Until recently I hadnt come across this fantastic design in real life.
This is the blue version of “Faenza”, Arabia Finland 1973-1979.
The very functional, clean lined forms (The EH Series) were designed by Peter Winquist, for which he won an international ceramics design prize.
The decoration/design is by Inkeri Seppälä (better known as Inkeri Leivo) .
The decoration on Faenza came in brown, black, blue and yellow- and the blue is such an intense, vibrant colour – and tends to be the more collectable (and thus expensive version nowadays). As far as I have been able to find out the yellow and black were without any pattern, just the banding.
