A detailed technical patent diagram of a double bass fills the composition with intricate line work and labeled components rendered in black ink on white paper. The drawing captures both the instrument's full body and numerous close-up details of its mechanical parts, creating a dense, schematic mood that celebrates the bass as an engineering marvel as much as a musical object. 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.
