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. Hand-stretched to order over pine stretcher bars and set into a wood frame, with hanging hardware included. The frame adds a clean, finished edge around the gallery-wrapped canvas. It arrives ready to live on your wall out of the box.
