This book features nautical imagery, sea shells, and undersea life. Drawing styles and line widths vary widely. Some pages repeat the same image in calming patterns, like one page with rows of sea horses, others have overlapping images until the overall effect is surreal, and others look like a colorful scene under the sea. The 8 1/2 x 11 pages are perforated, bound with staples (the book lays flat) and printed on thick, good quality paper. My favorite pages include a series of ships, compasses, anchors, helms, and spyglasses, with winding dotted paths connecting them all, with phrasing added like, “Summer,” “Free,” and “Trip Around the World.” Another favorite is a series of different types of whales covered in wavy lines, dots, and other patterns. Especially for those with interest in the sea, this is an appealing and well-designed all ages coloring book.
