A technical patent diagram for a baseball dominates the upper portion of this chalkboard-style illustration, rendered in white linework against deep charcoal gray. Below sit two detailed cross-section views showing the ball's internal layered construction, with measurements and annotations completing the scientific breakdown of this classic American sport's fundamental object. For a sports enthusiast's office or a game room celebrating athletic heritage. Printed on glossy aluminum and made to order, ready to hang with the hardware built into the back. Original artwork in a finish that holds its color and resists fading, not a quick print off a shelf.
