Thanks for the input majestic and chachi! Yea, I would think a bigger red flag would be if the entire flag was done in the same handwriting, but I guess I am where I started with maybe real, maybe fake. I will say if this is a fake, whoever did it put some effort into it to say the least, with aging stains and some slight fading/discoloration, and it seems the Samuhara Kanji wouldn't be a common thing to be faked, but who knows. I still think its pretty neat, and I'm glad I purchased it, as a nerd for history.
