It is the cover page of the "Wara Ippon no Kakumai - Sokatsuhen", subtitled "Nendo Tango no Tabi", which he published after his travels to the US, Europe, Africa and India. The equivalent English publication is called "Recapitulation". Nevertheless, the latter is not a translation, since the contents of both book is quite different.
Thanks, Dieter. Yes, it was a rather lovely book. Lots of colour pictures. He gave a copy to my wife when she attended his course in 2002. At the time, he was around 90, could not walk and had to be carried everywhere.
The yapparikenkou site is the only place I've seen it for sale, so that's why I'm looking for someone who can help me with the purchase.
