A Sioux spontoon tomahawk is set to lead Heritage Auctions' sale of Native American artefacts in Dallas.
The lot is valued at $60,000-80,000 ahead of the May 15 sale.
Spontoon refers to the diamond shaped blade.
Heritage comments: "Various types of tomahawks were ubiquitous among the many tribes from the East Coast across the larger portion of the United States and Southern Canada to just west of the Rocky Mountains.
"Evidently in the 17th century, "tomahawk" came into the English language from the Algonquian-speaking Powhatan Tribe of Virginia...
"The overall characteristics of the beadwork and quillwork of this tomahawk serve to attribute it to the Lakota / Western Sioux tribe, presently divided on several reservations in North and South Dakota, and Montana."
A Crow beaded hide cradleboard is likely to prove another highlight, with a valuation of $50,000-70,000.
The lot dates to around 1890 and allowed plains mothers to transport their children on their backs or attached to a horse.
