Picked this cup up (sans saucer) a couple of months. It's Kaj Franck's 'Kilta' for Arabia of Finland. The line launched in 1952, it's functionalist form was quite revolutionary for the time. Pure form with no embellishments, it's concept was to be a democratic dining service both simplified and affordable to the masses. And no, Crate & Barrel didn't come up with the square white plate!
