Two elongated baseball bats dominate the center of this technical patent drawing rendered in white linework against a dark charcoal ground, with detailed cross-sectional views and end-grain diagrams arranged to the right. The composition captures the precise, methodical language of early industrial artwork, using the austere palette and formal layout of vintage patent documentation to elevate a simple sporting tool into something worthy of scientific study. 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.
