I had this piece listed for 10 minutes before it sold. This was a mint condition Catherineholm relish tray. I happened to spot it on a back shelf in a consignment shop. Grete Prytz Kittelson is said to be one of the best known Norwegian designers in the Scandinavian Movement. Kittelson participated in the "Design in Scandinavia" exhibition from 1954 to 1957. Towards the end of the 50's her products were manufactured by Catherineholm and her enamelware could be found in many Norwegian homes.
