Topic: Trad'l Archery from Six Continents: The Charles E. Grayson Collection
I have the book, but I also found a pdf of it. If you don't have it, I strongly recommend buying it before you download the pdf.
I helped Bert Grayson obtain several of the items in the Korean section of his collection (Happily, my name was associated with a few of them in the book), especially arrows (although I did help him get a few bows).
My only regret is, although Bert and I considered each other friends for many years, we never actually met face-to-face; we communicated by phone, snail mail and e-mail. He had always intended on visiting me here in Korea, but the year he was going to, his doctor advised him against flying long distance. When he passed away, I felt like I lost a member of my family, which, in a way, I did (My archery family).
