This is a square plate I purchased at an antique market. I liked the bird's eye view and brought it home. Below, you can see the sea. You can see the waves. Clouds are also drawn, so perhaps it's flying high up. The body has geometric patterns all the way around. Marked. Ken. There are several chips on the edge. Please check the images carefully. Otherwise, it seems to be kiln marks. Size: Width: Approximately 16.5 cm Depth: Approximately 11.5 cm Height: Approximately 3.3 cm
