How the 1860s imagined the city of the future: a black-and-white wood engraving illustration from a Victorian illustrated weekly, filling the whole image as the artwork itself. A grand avenue roofed entirely in iron and glass, steam-powered omnibuses on rails, passenger balloons tethered to towers like ships at a pier, a moving pavement carrying ladies in crinolines and gentlemen in frock coats, smokestacks everywhere and soot in the air. Dense cross-hatched engraved lines, crisp black ink on off-white paper, slight paper texture. No caption, no text, no letters, no signage.
