Antique items with the same design are very expensive, but this is not a bargain. It's for everyday use, and there's a small color unevenness between the pine tree and the roof in the design. I think it's a "blemish" item. Therefore, there is no mark on the back. How about using it as a unique plate for snacks, etc.? Size: 17 x 12 x 3 cm Please understand that this is a retro, used item that was in my grandmother's house.
