Thank you for viewing. This is a white ceramic sake cup featuring a distinctive blue line drawing pattern, inherited from my uncle. A small piece of paper is included, which states: "This sake cup was made to commemorate the completion of the palace, using the design of the wall pattern in the Matsu-no-Ma (Pine Room) of the Seiden (Main Hall). Imperial Household Agency." Based on this description, it is believed to have been made to commemorate the completion of the new Imperial Palace in November 1968, which replaced the Meiji Palace that was destroyed in the air raids of May 1945 (Showa 20). The Matsu-no-Ma (Pine Room) of the Seiden (Main Hall) is used for major ceremonies such as the New Year's Celebration, the Presentation of Credentials, the Appointment Ceremony, the Conferment of Decorations, the Ceremony of the First Lecture of the Year, and the Imperial Poetry Reading. - Design: White ceramic sake cup with a blue line drawing pattern - Shape: Circular design with a flared base - Manufacturer's mark: A small mark on the bottom, likely indicating the Fukagawa Seiji brand.
