 Lehmann was a very popular figure in southwestern Oklahoma and the Texas Hill Country, appearing at county fairs and rodeos.To thrill audiences, such as he did in 1925 at the Old Settlers Reunion in Mason County, he would chase a calf around an arena, kill it with arrows, jump off his horse, cut out the calf's liver, and eat it raw.His second autobiography, "Nine Years Among the Indians" (1927, edited by J. Marvin Hunter) was at the request of Lehmann.
