Foaming Atlantic swells explode against the dark layered rock shelves of Mar del Plata's coastline in this vivid hand-colored Argentine postcard, the spray frozen mid-air in twin white geysers while a lone vessel sits on the turquoise horizon — "Temporal en la costa" (storm on the coast) captures the wild drama of the Pampas sea-resort that had become Argentina's most fashionable summer destination for Buenos Aires society by the 1900s, and this card, published by Librería Rey on San Martín street in Mar del Plata itself, is a local production artifact that rarely surfaces outside South American collections, making it a distinctive find for Latin American topical collectors.
