A technical patent diagram for a baseball dominates the upper portion of this chalkboard-style illustration, rendered in white linework against deep charcoal gray. Below sit two detailed cross-section views showing the ball's internal layered construction, with measurements and annotations completing the scientific breakdown of this classic American sport's fundamental 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.
