This is a serving tray that at one time was either bought by your great grandfather or presented to your great grandfather in Japan. It is a handmade tray with inlaid mother of pearl. These were given to service men for favors of help or money. They were crafted by the finest artisans. It looks to be in excellent condition and kept in a hand custom box for protection is perfect as the inlay can become loose or chip out because of age. these trays were for meats or tea cake type foods not heavy foods that had sauces or such that would destroy the beauty. From the look of the tray I doubt it was ever used and had been treasured over the years for the beauty. The tray is valued at 550-650.00 in today's market.The size, material and condition is the biggest selling point. Also, you have the providence to the piece and be sure to write down where and when he brought the piece home. This confirms the age and time piece. It is a beautiful piece thank you for the photos and sharing this with us. If I may be of further service please let me know as I am happy to help.
