A vintage patent diagram illustrates the dimpled surface and cross-section of a golf ball in precise technical detail, rendered in grayscale with fine line work and hatching. The composition is vertically organized with multiple spherical views and sectional drawings, capturing the methodical aesthetic of early scientific documentation with authentic aging and texture throughout. 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.
