The image is a line drawing in black and white, depicting two primary figures within a simplified landscape. The landscape consists of a ground line and three cloud-like shapes depicted with freehand outlines.The first figure, predominant in size and occupying the majority of the visual space, resembles a cartoon-style dinosaur. This entity is characterized by a large, rounded body with patterns that consist of multiple circles and spots. The head of this dinosaur is positioned to the left, while the tail extends to the right. Notable features include forward-facing eyes, a petite smile with visible pointed teeth, and a rounded snout. The limbs are stylized with simplified foot shapes, and the creature appears in a prone position.The second figure is significantly smaller in size and is positioned on the back of the depicted dinosaur. This figure is a cartoon-style horse, differentiated by equine features, such as a raised tail, mane, and a snout indicative of a horse. The horse is kitted with a saddle and reins, suggesting domestication.Both figures and the clouds are outlined with a uniform line weight, suggesting the line art is intended for coloring or educational purposes, often found in children''s activity books.
