Lengthy AMS in pencil, signed at the head, "Zane Grey," 36 pages (numbered 1-30 and 38-43, but appears complete), 7.75 x 12.5, no date. Grey's lengthy handwritten manuscript for an evidently unpublished piece entitled "The Greatest Man I Ever Knew." The piece begins: "His name was Jim Smett. He was a Mormon. He had been born in a covered wagon crossing the plains, and all of his life had been lived in the desert. He told me that five nights out of every seven he had slept out, on the sand and the rocks, or under the pines. No wonder he was great." In fine condition. A fantastic and unusually long manuscript from the well-known author, whose tales of the American West have captivated readers for over a century.
