A technical patent drawing from 1925 illustrates a basketball in three detailed views, rendered in precise black line work against a clean white ground. Labeled diagrams show the sphere from multiple angles alongside two cross-sectional views, capturing the mechanical specifications of the ball with the formal clarity of vintage scientific documentation. Constructed from woven polyester with a soft microfiber lining and a sturdy zipper, made to order for 13 and 15 inch laptops. Everyday protection carrying an independent artist's work, not another plain black sleeve.
