Anastatic 7-color reproduction of the original chromo-lithographic editon of Giuseppe Mengoni's project for the Vittorio Emanuele gallery and renovation of the city's main square. Drawings are on a scale of 1:100, and may be the first application of axonometric representation for an urban renewal scheme. Top right, a general plan for the square's clearance scheme. Drawn by G. Landriani and L. Burlando, orginals of this highly detailed and rather ornate lithograph are very rare.
