This image portrays two Comanche braves on horseback. One is holding a cavalryman's bugle in an exuberant manner while the other is grinning in approval. How the Comanche got the bugle is never known: did he find it or was it a prize from battle? The story is left up to you, the viewer, to decide.
The Comanche were once a powerful and large tribe who roamed a vast territory. This setting could be what is now Texas, party of the area the Comanche Nation inhabited.
