Zermatt And Its Valley … delightful book online

A wonderful book written by Francois Gos, which was translated into English and published in 1927.  Fantastic black and white photographs, and a detailed history of all the towns leading up to Zermatt, the various hamlets and alpine pastures, as well as the important peaks.
