Issued in 1963, this 80 centavos Correo Aéreo (airmail) stamp from Mexico commemorates the Jornadas Internacionales de Arquitectura — International Conference on Architecture. The design depicts a striking architectural relief from the Universidad Iberoamericana (UIA), symbolizing Mexico’s growing modernist influence in mid-20th-century architecture. The bold geometric forms and grayscale tones reflect the period’s architectural aesthetic, merging academic and artistic traditions. Printed by Talleres de Impresos de Estampillas y Valores, this issue honors Mexico’s role as a hub for international cultural and academic exchange.
