GIOVANNI B. PIRANESI Veduta di Piazza Navona sopra le Rovine del Circo Agonale. Etching, 1751. 410x547 mm; 16¼x21¾ inches, wide margins. Second state (of 6), with the lettering and signature, but before the address and price, with the drypoint guidelines for the text in the lower margin distinct. Fleur-de-lys in a single circle watermark (Hind 1, which he notes for early impressions before the address and price). From Vedute di Roma. A superb, early impression with strong contrasts and no sign of wear. Hind 16.
