A black and white engraved map depicts the Great Lakes region and surrounding territories with fine linear detail, labeled place names, and decorative cartouches typical of 18th-century cartography. The composition fills the rectangular frame with intricate coastlines, waterways, and geographical features rendered in precise crosshatching and delicate line work. 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.
