A detailed topographic map rendered in black ink and blue watercolor depicts the Great Lakes region with its intricate shorelines, elevation contours, and geographic features spread across the composition. The muted palette and precise cartographic line work convey both scientific accuracy and a contemplative sense of vast natural geography. Constructed from woven polyester with a soft microfiber lining and a sturdy zipper, made to order for 13 and 15 inch laptops. Everyday protection carrying an independent artist's work, not another plain black sleeve.
