Three classic video game controllers are rendered as technical patent drawings in black ink on a white ground, arranged vertically to show their evolution from top to bottom. The meticulous line work and cross-hatching typical of patent illustrations give these familiar gaming devices a scientific, historical gravitas that celebrates their artwork legacy. 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.
