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. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
