The Horse coloring book contains original illustrations of horses and is appropriate for any age. The horse illustration on the cover is not colored realistically and is intended to inspire imagination and to allow for coloring freedom. The easy to color horse illustrations are drawn with unique fine outlines, with little extraneous imagery, without great detail, but with a moderate approach to realism. The 35 illustrations are printed only on one side of the 8.5" by 11" pages so colors don't bleed through when using water color markers.
