I was book shopping a few weeks ago and found this interesting book in a bargain bin ($6). Since I like to take pictures of interesting walls and building details it attracted me.
Title: It's a Great Wall
Pictures and text by Michael Webb and Arnold Schwartzman
It is a book of pictures of walls and stories about the communities they are in. it is a real easy and light read, plus it is a short book 150 pages.
The book is broken into four chapters, Synbolism, Protection, Materials and Ornaments. Each highlighting the function, or lack thereof, of walls.
Most interesting picture and essay is on teh walls in the fields of Ireland. Really neat aerial photo.
