Zui Kotō Kensō, Saikontan Zui Kotō Kensō, Saikontan This is an old book. It seems to have been published in the Taisho era. The color has faded, and it's quite old. It was at my parents' house. I think a relative probably received it from the library of an educational institution sometime before. There are imprints and stickers of the school facility name, as well as imprints indicating that it was removed from the collection. Please be aware of this. China
