Recently my wife and I decided to start collecting Cathrineholm enamelware. They were designed Grete Prytz Kittelson in Norway in the late 1950s. They have become extremely collectible and sell for a premium on Etsy and Ebay. We are dedicated to finding them the old fashioned way and in the last two weeks we have found two of them. I bought the white and blue piece from another picker for $20. My wife picked up the white and green one for $5 at a garage sale. These pieces commonly sell for $80-$120 but we are going to keep them.
