The copper body has an applied silver rim and silver base plate. It has a semi-matt purple-brown enamel ground decorated with a single peony blossom on a stem, which has been executed in brass yusen enamels. The petals of the blossom are in shaded white and purple moriage, while the leaves are flush with the surface of the vase. This combination of raised petals and flat leaves gives a sense of depth to the composition. The counter-enamel is of matt dark-blue enamel, as is the interior of the foot, which has the silver yusen mark of the Ando Company. Stylistically, and according to the Ando Company archivist (private communication from Mr Yoshida), the vase is likely to have been produced during the Taisho period (1912-1926). However, it is known that this design continued to be produced in post-war years, hence the date span given above.
