The true first edition published in September 1914 with no other printings listed. This is a review copy blind-stamped with ""Compliments of the MacMillan Company"" on the title page and a paper review slip laid in. Tight binding with no sign of cracking. I would grade this as a very good minus copy because of a faded or bleached streak on the spine and a gouge on the pasted-in photo on the front cover. Photos are the best description. No writing. The Kolbs, Emory and Ellsworth, are true Grand Canyon legends who pioneered the art of photography is a harsh wilderness environment. For years they persevered in an environment in which they had no real legal standing- their studio was built on a mining claim (not theirs) and both the railroad and the park service wanted them out. Finally an agreement was reached that allowed them to stay in their studio for life, at which time their studio would revert to the park service. Emory took full advantage of this by refusing to die- he remained in business until shortly before his death at age 96. This book is a description of their trip down the Green and Colorado rivers in 1911, only the eighth expedition to make a complete run of Grand Canyon. They also made a movie about the same tri60, which was shown in the Kolb studio on the rim for decades, until Emory died in 1976.
