A technical patent diagram of football pants rendered in white linework against a black chalkboard ground, showing front and back views with detailed annotations of pockets, padding, and construction seams. The composition captures the precision and instructional clarity of vintage patent illustrations, executed with the hand-drawn quality of chalk on slate. 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.
