Issued in 1978, this elegant pair of Mexican airmail stamps celebrates the Señorita Universo beauty pageant held in Acapulco. Designed by Lala Silva, the stamps feature a stylized female silhouette posed before a golden Aztec calendar, symbolizing Mexico’s rich cultural heritage and modern international spirit. Printed in red (₱4.30) and green (₱1.90) variants, the designs blend tradition with glamour, marking Acapulco’s prominence as a world-class event destination of the late 1970s. These issues are a fine example of Mexico’s artistic approach to commemorative philately during the era.
