I've been seeing alot of this vintage enamelware around lately. There is one scene in the movie Running With Scissors where they focus on a green Catherineholm teapot right before the mother blows her lid! You can also find a happy yellow bowl on the cover of Blueprint magazine this month. I wonder though... Does enamal rust? Many of the Cathrineholm designs were created by a woman named Grete Prytz Korsmo, wife of architect Arne Korsmo. Catherineholm was the name of the manafacturer in Norway.
