A historical cartographic representation of Lake Michigan's coastline and lighthouse locations rendered in muted earth tones and soft greens, with hand-drawn typography and fine linework characteristic of late 19th-century mapmaking. The composition balances geographic detail with decorative elements, including inset maps and a legend, creating a document that functions equally as navigation tool and nostalgic artifact of maritime history. 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.
