Softcover. Very good. No publication information given. 72 pages, in stapled pictorial covers. Includes general information about the Montana Stockgrower's Association, Livestock Commission, and brands, followed by drawings and ownership information on approximately 45 historical brands and 950 then-current brands, all of which were "cut out of copper sheeting and riveted to the side of the Centennial Train" -- a promotional/publicity train that eventually made its way across the country to the New York World's Fair.
