There is plenty of history in Ms. Kasson's book, but history itself isn't really the point; the point is to examine and analyze Buffalo Bill's Wild West as a representation--often a conscious, sophisticated one--of the American frontier.
I found many things in this book interesting and surprising. To name just four:
1) For approximately ten years, Buffalo Bill was both a frontier army scout (summers) and a New York actor playing himself in a series of melodramas (winters). After accomplishing his most famous exploit--the killing and scalping of Yellow Hand in retaliation for the Little Big Horn--he almost immediately telegraphed a New York department store and arranged to have Yellow Hand's regalia displayed in one of its windows.
2) The Native-Americans in Buffalo Bill's Wild West viewed their work as a more honorable form of employment than most others because it involved the skills of riding and shooting, and some even viewed the performances themselves as an extension of their battlefield prowess. (In fact, a Lakota warrior once stood in the empty arena at the close of a season, singing a praise-song for his brave deeds during the year.) Also, the Indians themselves had some control over the use of their images, at least outside the show itself; in one instance, Iron Tail and his people refused to have their picture taken with a statue of Christopher Columbus.
3) Using the Wild West as a model, its promoters launched another venture that tried to treat African-Americans with the same pretense to authenticity and historical reverence as the Wild West in a presentation called "Black America," containing everything from songs and jigs to simulated slave auctions and a working tobacco factory. It never caught on.
4) Although Buffalo Bill was a heavy drinker and an imprudent custodian of his own money, he had entrepreneurial and marketing instincts well ahead of his time. The town of Cody, Wyoming was founded partly as an opportunity to market real estate and tourism in an authentic, Buffalo-Bill-endorsed Western location not far from Yellowstone Park, featuring not only the fully equipped modern "Irma Hotel" (named after Cody's daughter) but also the more rustic log-cabin structure, the "Puhaska Teepee," for those with an appetite for a slightly wilder West.
Kasson's book is well-worth your time. Paradoxically, by focusing on the purity of the Wild West representation, the author reveals the historical complexities and contradictions, and brings Cody's era closer to our own.
