A technical patent drawing for an acoustic guitar rendered in white linework against a charcoal black ground, showing three detailed views of the instrument from different angles with period signatures and patent information dated May 2, 1893. The composition combines the precision of architectural draftsmanship with the organic curves of the guitar's body, creating a striking interplay between mechanical clarity and musical form. 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.
