A work of great charm and prestige, created in July 1959 by Mario Cortiello, one of the protagonists of 20th-century Neapolitan portraiture. The painting depicts the wife of an Argentine diplomat, captured in an elegant pose on a balcony overlooking the Gulf of Naples: an emerald green dress, a pearl necklace, and a small dog at her feet create an atmosphere of refined intimacy. The oil technique reveals the artist's mature hand: soft layers, delicate washes on the faces, fuller brushstrokes on the fabrics, and a luminous palette that enhances the scene. The work is signed and dated, on the first canvas, with authentic preservation consistent with its period. The diplomatic provenance lends the painting added value, making it particularly attractive to collectors of 20th-century portraiture, enthusiasts of the Neapolitan school, and buyers interested in works with documented patrons.
