Circa 1900. Photograph postcard measuring "11 x 4" with 9 cowboys and 2 chuck wagons, followed by horses and cattle. The card was mailed January 20, 1910 from Montana with note on message part of card: "a picture of the Long X Roundup taken from life." Both a nice photograph of a roundup that typically would cover the south half of Powder river County, Montana and the north half of Campbell County, Wyoming. The Long X Ranch was the largest and most famous cattle ranch in McKenzie County (North Dakota Hall of Fame). The Reynolds Brothers from Texas bought it and soon after Theodore Roosevelt built his ranch at about the same time in the region. The Long X had the reputationof doing business in the most economical way of any ranching concern in the West. Like TR they lost a large part of their herds to disease and a cruel winter, they eventually sold the business to the Converse Cattle Company. Much of their land is now part of the Theodore Roosevelt National Park. Nearby Killdeer is the hub of Cowboy County and the home of North Dakota's oldest PRCA rodeo. Crease in middle to facilitate mailing. A good copy of an apparently unique item.
