This is a Schumann Arzberg plate with a watermark, founded in Bavaria, Germany in 1881 and manufactured until 1994. Size: Approximately 19cm in diameter. Shipping will be via Rakuraku Mercari Bin or Yu-Yu Mercari Bin, using a suitably sized box I have at home. It is almost unused, but it is a very old item. There are some minor scratches that occurred during long-term storage. Please understand that this is a vintage item that has been stored at home for a long time. Only those who understand that it is an old item and a vintage item are welcome to purchase.
