I will repost this accurately. According to sources, this is highly likely to be either a "copy or a fake." In other words, it is highly likely not to be the original manuscript. Recently, I have seen reports of private auctions and underground transactions where such Japanese manga and anime-related goods are being traded at exorbitant prices. It is a tragic loss of historical materials when rare items and valuable documents of unknown origin end up in inappropriate places. In my opinion, these genuine items should definitely be protected by the appropriate places and institutions.
