A technical patent drawing from 1928 displays baseball equipment in meticulous black line work against a clean white ground, with a bat, ball, and detailed cross-sectional diagrams of the ball's interior construction arranged in a methodical grid. The composition carries the instructional clarity of early-twentieth-century patent documentation, rendered in precise pen strokes that emphasize function and engineering innovation over decoration. 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.
