A vintage star chart rendered in deep navy blue and white presents the constellations in precise geometric detail, with delicate lines mapping the celestial sphere across concentric circles and coordinate grids. The classical astronomical illustration combines the rigor of scientific cartography with the timeless appeal of early 20th-century astronomical documentation, its faded patina suggesting centuries of careful study. 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.
