Design a poster titled "Tardes de JAzz" in an elegant art déco style with a dark palette of navy blue and black, accented by gold, silver, and white. The poster features the title in large, golden letters at the top, set against a starry night sky background. The central element is a stylized illustration of a golden saxophone and vintage microphone, surrounded by floating musical notes and silhouetted musicians on a minimalistic stage, softly illuminated. The sides of the poster are framed by silver vine decorations, adding a touch of natural elegance. Below the illustration, a sleek section provides details on the date, time, location, and a brief invitation in white text, contrasting against the dark background. The bottom of the poster is adorned with small star-like sparkles, with space for sponsor logos or additional information.
