This is a Showa-retro picture frame. It is about 3mm thick. Available for immediate purchase. Please feel free to negotiate the price. This was made by my grandfather, who ran a carpenter's shop about 50 years ago, and has been stored in a dark place. Please be aware that it is not in pristine condition as it has some stains, so please be careful if you are sensitive to such things. When packing, we will take measures to prevent water damage and breakage. Showa Retro Retro Vintage Antique Japanese Modern Vintage Modern Picture Frame Art Painting Paintings
