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. Bound with 52 pages of 70lb paper, lined or unlined, behind an anti-scuff matte cover with wraparound artwork, made to order. Notes and sketches kept behind an independent artist's work, not a plain composition cover.
