Either a hardcover book of photographs
by National Geographic photographer, Steve McCurry, or the set of postcards
used by Atum as a workshop exercise, can
be purchased online through Amazon.
The book is a bound set of the images at the same size as the
postcards, without any additional text. There are actually quite a few
more portraits in the book than the 50 included in the set of cards.
Book and CD set used by Reb Zalman at SGT program in Boulder, CO.
Purchase information available from Wisdom of the World website. The
book and 2 CD version is out of print, but they will send you all of
the same products separately for the package price.
