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. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
