A vintage patent diagram shows a baseball at the top with detailed stitching patterns, followed by two unrolled views of the ball's construction and seam layout below. The composition is rendered in simple black line work on a weathered cream background, capturing the technical precision of early 20th-century patent illustrations with their characteristic sparse, informational style. For a sports enthusiast's office or a game room with vintage character. Printed to order on smooth 100lb gloss paper, then rolled into a tube and shipped ready to pin, tape, or frame. Sized to fill a wall without filling the budget. The same independent-artist artwork you'd frame, at poster scale and poster price.
