Issued by Mexico in 1976, this modernist commemorative celebrates the national exhibition “México Hoy y Mañana” (Mexico Today and Tomorrow), symbolizing progress, industry, and future development. The bold geometric logo in red and green reflects contemporary 1970s graphic design trends, giving the stamp strong visual and thematic appeal. The inscription “Palabra Cumplida – Exposición” emphasizes commitment and achievement. Designed by O. López Márquez, it represents Mexico’s modernization era and socio-economic optimism. A desirable piece for collectors of exhibitions, propaganda themes, and Latin American modern issues.
