White technical line drawings of a fire hydrant appear across a dark charcoal background, rendered in the style of a vintage patent schematic with detailed mechanical views and cross-sections. The composition balances multiple perspectives of the industrial object with handwritten annotations and official patent markings, creating a cool, technical mood that celebrates industrial artwork 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.
