In 1910, Santa Fe reissued Titan of Chasms with a new cover. Although four pages longer, the newer booklet contained the same three essays as the 1902-1909 editions, but rearranged with new graphics and photos including photos of each of the authors. (The photo of Lummis is the one used in his Wikipedia entry.)
We’ve previously seen the wrap-around cover painting on a Santa Fe menu. The artist is William Robinson Leigh, who was known as the “Sagebrush Rembrandt.” The Santa Fe paid his way to the Grand Canyon in 1906 and then bought five of his paintings that it hung in El Tovar and other Grand Canyon lodges. This painting is dated 1909 so must be from Leigh’s second trip to the canyon, which was also sponsored by the railroad.
