No maker signatures believe it was from a galley not a factory, but I received it inside a storage unit and the owner who gave it said they paid about $20,000 in 1980s i just know it is made with jade,serpentine, granite, quartz, etc and a tiger landscape. The back is a hand‑painted lacquer scene with mountains, bamboo, bridge, figure, birds, etc. Was told by AI that it might have been in the middle of a walkway for walk around presentation. THIS FRAME IS SOLID WOOD all around Only 1 small piece of granite has fallen inside the glass frame
