Plains artists used a variety of methods to record their activities. An artist could draw or paint a scene, and use it as a visual tool to tell his story.
In this drawing Old Bull depicts three scenes of a horse raiding expedition against the Apsaalookas (Crows). All of the men are wearing wool leggings and hooded capotes, clothing worn when it was cold. The story begins in the lower right corner, showing the artist and his comrades leading a group of horses away from an Apsaalooka village. A battle ensues forcing Old Bull and his men to take defense behind a group of large boulders, shown in the middle of the drawing. The final scene was drawn in the upper right corner where Old Bull has loaded a wounded young man on a travois.
The labeling and lines that separate the different scenes were probably added by a collector in an attempt to make the story easier to understand.
