The middle dish was my grandma's, and it wasn't until recently that I discovered it was part of a set. The three dishes were made by the Porsgrund porcelain company and are called "The Old Story." The first shows a couple like Adam and Eve, complete with apple tree and snake. Next the couple have a small child, a house, and a cat. Finally, the couple is older and joined by their children and grandchildren. The dishes were designed by Anne Marie Odegaard and Konrad Galaaen and are glazed in a flow-blue-like glaze. Apparently the three dishes were sold together in a box with a short poem called "The Old Story."
Each of my three dishes has a different mark on the back. Each dish has the Porsgrund logo with the anchor, PP, and Norway. The other two dishes have the years of manufacture: 70 and 68. Each dish also has it's code number: All of them have M.2303; under that they have (from left to right) D.78009, D.78010, and D.78011.
