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. Water-resistant polyester, hookless and cut extra long to fit any bath, machine washable and made to order. It turns the bathroom wall into the room's best feature.
