A detailed technical patent drawing displays three views of a tennis racket alongside cross-sectional diagrams and component specifications rendered entirely in black ink on white paper. The composition captures the mechanical precision of early 20th-century patent illustration, with fine lines and numbered annotations documenting the racket's construction from handle through the woven string head. 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.
