A detailed street map of Chicago rendered in white lines against a black background, with the grid of neighborhoods and thoroughfares creating an intricate urban geometry. Lake Michigan forms a dark void along the eastern edge, emphasizing the city's relationship to the water and the cartographic precision of the composition. 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.
