The importer is Zoo Book Sales (http://www.zoobooksales.com/photogal/chi-chamafr.htm). I'd call Eric and Anne directly before ordering from anywhere else. They ship very quickly and it'll arrive just a couple days after that .
the first time I´ve heard about the book is four or five years ago (can´t realy remember)
but me and one of my freinds have asked for it ever since...
and there have ben many delays, I belive it was a two years delay(since I orderd it for the first time)
because Tilbury always had some new changes... but finally after about 30 years of observing theese animals
this great book arived in a few copys at last Hamm show (in sep.)
although I do not agree with every thing in the book ... I still think it´s the greatest book about chams in the wild .
