Sulfurous steam billows from the throat of an ancient volcano in this dramatic, almost cinematic real-photograph postcard of La Solfatara di Pozzuoli — the dormant volcanic crater near Naples where the ground bubbles, hisses, and breathes as it has since Roman times, when the emperor Augustus himself came to take the medicinal waters. The image captures the crater's raw, otherworldly interior: a gully of pale volcanic rock split by a rushing plume of steam and sulfurous gas, the hillsides bare and alien, a path winding toward the fumarole as if daring the visitor to approach. La Solfatara (part of the Campi Flegrei supervolcanic system) was one of the great natural spectacles of the Grand Tour era and remained a top tourist attraction into the 20th century. This card was sold on-site — the reverse bears a striking oval purple proprietor's stamp reading "Solfatara di Pozzuoli / Proprietà DE LUCA," identifying the De Luca family as the private owners of the Solfatara site (as they indeed were for generations — the De Luca family owned and managed the Solfatara park from the late 19th century through the tragic 2017 accident that claimed three lives and led to its closure). Published by E. Ragozino, Art Store, Galleria Umberto I, Naples (card no. 8305), this is an exceptional piece of Campanian tourist and volcanological ephemera.
