I remember that when I was about 12, I bought Nitobe's Bushido. It was from the same publishers as Black Belt Magazine, Ohara Publications, a small paperback with absolutely beautiful photographs of trees, beaches,etc. I especially remember a photo of grass that looked like a bunch of swords sticking up. It was a magical book at that, for me, a magical time, reading about honor, chivalry, benevolence. A world that was quite different from the one I was experiencing around me.
I don't know if you read the post exchange between PAG, and myself where we discussed, in a different thread, Nitobe. In that discussion I quoted Nitobe, from a copy of the same book you remember. I too like it.
