The image is a sketch showing a three-quarter view of a person seated on a horse. The person is sitting upright on the horse, facing slightly to the right side of the image. The facial features of the person are not visible in detail, but the person appears to have short hair and may be wearing a cap. The person is wearing a long-sleeved garment with a loose fit. The horse is partially visible with a focus on its front half, showing the head, neck, and part of its torso. The horse's mane is illustrated with lines indicating texture. The saddle and blanket are ornately decorated with geometric patterns. There is a note within the sketch that reads "Red." The background is plain and consists of clean, empty space. The drawing is signed "Larry Rivers" at the bottom right corner.
