A technical patent drawing of a pinball machine dominates this composition, rendered in black ink on a white ground with the word "PINBALL" anchored at the top. The diagram explodes outward in an intricate web of mechanical components, numbered callouts, and cross-sectional views that reveal the ingenious engineering beneath the game's surface, capturing both the complexity and the playful spirit of mid-century arcade artwork. 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.
