I have a copy of this book signed by the Japanese peony society. My google search to find another that was selling failed but it did bring me to this website. If you or anyone in your group are interested in purchasing it or seeing some photos, let me know. The last one I could find any information on was on yahoo auctions in 2009 according to "Daves Garden", a random blog that talks about the book.

Thanks for your time,

Jake Kelbrants
