Amos Bad Heart Bull

Amos Bad Heart Bull, also known as Waŋblí Wapȟáha (Eagle Bonnet) (ca. 1868-1913), was a noted Oglala Lakota performer in what is called Ledger Art. It is a style that adapts traditional Native American pictography to the other European medium of paper, and named for the accountants' ledger books, available from traders, used by the artists for their drawings and paintings. He was furthermore the tribal historian of the Oglala, as his dad Bad Heart Bull (Tȟatȟáŋka Čhaŋtéšiča) was before him.
