Thank you for viewing. Please check my self-introduction for important notes regarding transactions before considering a purchase. This is a Go board from about 50 years ago. It has legs and a "heso" (the indentation on the bottom). Height: Approximately 29cm Go board thickness: Approximately 16.5cm Weight: Approximately 14kg There are characters and a signature on the back. It is probably the name of the maker, but the maker is unknown. There are chips on the corners, and overall signs of aging are visible. I do not know the material, and I am not an expert, so please make your judgment based on the images. As this is an old item, please check the photos carefully and purchase with the understanding that it is used.
