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. 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.
