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