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. Sewn from a durable canvas-like exterior with a soft lining and made to order, in three sizes up to one that fits a tablet. A catchall for toiletries, art supplies, or small electronics, carrying an independent artist's work instead of a plain zip bag.
