In a Shirt, Indian Family Sees Its History Ten years ago, lost to drugs and alcohol, Karen Little Thunder moved back to the Rosebud Indian Reservation in South Dakota, where, she said, she saved her own life by reconnecting to her Lakota heritage, particularly the legacy of her great-great grandfather. He was Little Thunder, a Lakota leader and a contemporary of Crazy Horse, whose life spanned several decades central to the history of the tribe - from the battles it fought across the Great Plains to its resettlement on reservations. A photo that some claim to be of the Lakota leader Little Thunder in a rawhide shirt. Sam A. Minkler for The New York Times Karen Little Thunder, a descendant of Little Thunder, on the Rosebud reservation in South Dakota. The family contends that the shirt is its property. "He was a great leader who always had the greasiest tepee door, because he was generous and was always feeding people," she said. Little Thunder, described by one trader as "six feet or more in height, handsome, with a commanding bearing and superior intelligence," led a band of Sicangu Lakota that lived along the Platte River, which runs east to west across what is now central Nebraska. He rose to prominence in 1854, after United States Army soldiers shot his predecessor Conquering Bear over a dispute involving a "ten-dollar cow that had wandered into a Lakota encampment from a Mormon wagon train," said Peter Gibbs, a retired curator of the Native American art collection of the British Museum, who has done research on the Lakota and has taught at a university on the reservation. In a photograph of a man the family believes to be Little Thunder, taken around 1860, he poses in an elaborate rawhide shirt. On the sleeves are locks of hair given to him by his people or perhaps cut from scalps taken in battle, as well as eagle feathers dyed red and white to symbolize the civil and war responsibilities of his office. Last fall, a history professor on the reservation contacted the family after noticing, in an auction catalog, a shirt that looked like the one in the photo. The Skinner auction house in Boston had listed it as a "Sioux Beaded and Quilled Hide Shirt" and estimated it would fetch between $150,000 and $300,000 at its Nov. 9 sale. But minutes before the bidding began, Skinner withdrew the item from the auction in response to pressure from lawyers and tribal officials representing the Little Thunder family. Karen Little Thunder is the main family member pressing the suit. "This is not just a pretty object that you go and sell," said Mr. Gibbs, who said the shirt has historical significance because of its former owner. Cultural property claims can be complex: The competing interests of good-faith collectors and plundered civilizations have to be adjudicated among complications like the passage of time, the disappearance of records and the evolution of law. Douglas Diehl, director of the American Indian and ethnographic art department at the auction house, would not discuss the matter when reached by phone, but released a statement saying that Skinner "is committed to the highest standards of research and due diligence" and is "particularly sensitive to Native American artifacts." The collector who consigned the item for sale, Charles E. Derby, said that he had good title to the shirt. He bought it, according to his lawyer, William H. Fry, from another collector in the early 1980s and has a bill of sale. Mr. Fry said his client could track the shirt, which has been shown in museums, back to 1955, when it was displayed, and later sold, by a bookstore in Cambridge, Mass. A lawyer for the Little Thunder family, Robert P. Gough, said that a collector would need a lengthier provenance for the shirt to claim good title. Mr. Gough is relying on a series of laws that restricted the buying and selling of land and personal property between Indians and white people. Some of these laws, which protected Indians from desperately selling their property for unfair prices, were in force until 1953, only two years before the shirt was purchased from the bookstore. A transfer, even a sale, of the shirt to a white person that took place before 1953 would have been prohibited by law, Mr. Gough contends, leaving only a two-year window for the shirt to have left the tribe. Mr. Gough says that no one in the family can remember such a transaction then. But Mr. Fry, the seller's lawyer, took issue with that reading of the Indian commerce laws. He said that the laws promoted an outdated and "paternalistic view" of Native Americans and that the last of them were repealed in 1953, at the request of Native Americans. "The law made it illegal for them to buy, sell and possess personal property - it treated them as wards of the state who were incapable of making their own decisions," he said. Since there are no known photographs of Little Thunder, Mr. Fry questioned how the family could even be sure the man in the photo was an ancestor.
