This drawing is a horse drawn using contour lines.  As you can see, it has the feeling of being a cartoon, and the figure is outlined all around in a thick black line.  It has no shading so there is no difference in value or hues in the work because it is strictly white and black.  Also, there is no stippling or hatching, just contour lines all around.  Angles are emphasized in this drawing as opposed to 3d forms.
