One from a Set of Five Soba Cups with Chrysanthemum Design

The image shows a white porcelain cup with a wide mouth and a narrow base. The cup is empty and appears to have some small brown and black specks inside. The interior of the cup is mostly white but has a small amount of discoloration around the rim. The background of the image is a plain gray color. The cup is likely one from a set of five soba cups with a chrysanthemum design, created by an unknown artist.
