Dish in the shape of a chrysanthemum flower (one of two)

Black and white photograph of two round dishes. Dishes have a ribbed exterior edge. Each dish has a series of concentric circles on its face, with the center circle being solid. The concentric circles are made of thin lines that radiate outwards from the center. The lines are thicker at the center and get progressively thinner towards the edge. The background is a plain light gray color. The dishes are placed side by side. They are titled "Dish in the shape of a chrysanthemum flower (one of two)" and are by an unnamed artist.
