1912 Wyoming Brand Book is a black and white facsimile reprint of the official brand registry published by the State of Wyoming in 1912, documenting the livestock brands, marks, and earmarks registered by ranchers and stockmen across the state. Brand books of this era serve as an irreplaceable primary source for the history of the Wyoming range cattle industry, capturing the names, locations, and registered marks of the ranching families and operations that shaped the character of the state during the open range era and its aftermath. Each entry records the owner's name, county, and the specific brand or earmark used to identify their cattle and horses — making this volume a uniquely personal and practical document of the working West. This facsimile reprint is an essential reference for genealogists tracing Wyoming ranching families, historians and researchers of the range cattle industry and Western land history, and collectors of Wyoming and Western Americana. Brand books are among the most distinctive and collectible categories of Western historical documents, prized for their direct connection to the ranching heritage of the Great Plains and Rocky Mountain West.
