Constitution and By-Laws and Brand Book of the Converse County Cattlegrowers' Association is a facsimile reprint of the original 1903 publication issued by the Converse County Cattlegrowers' Association of Wyoming — a rare and historically significant document capturing both the organizational governance and the registered livestock brands of one of Wyoming's active ranching counties at the turn of the 20th century. Unlike statewide brand books, this volume offers an intimate look at a single county's ranching community, combining the association's constitution and by-laws — which governed the conduct, membership, and cooperative interests of its stockmen members — with a registry of cattle brands, marks, and earmarks belonging to the ranchers and operations of Converse County. Together these two components paint a vivid picture of the organized ranching culture of the Wyoming range at a moment when the open range era was giving way to fenced and deeded land. This reprint is an invaluable resource for genealogists tracing Converse County and Wyoming ranching families, historians researching the range cattle industry and the development of stockgrowers' associations across the Great Plains and Rocky Mountain West, and collectors of Wyoming and Western Americana
