Issued by Mexico in 1962, this 40 centavos commemorative stamp celebrates the Feria Mundial — the Seattle World’s Fair, officially known as the Century 21 Exposition. The stamp features a stylized image of the futuristic Space Needle, the iconic symbol of the fair, depicted with modernist lines and geometric precision. The design reflects the theme of innovation and progress that defined the early 1960s world expositions. Printed in monochrome gray and green tones, it captures Mexico’s participation in a global celebration of science and technology.

Collector’s Note:
This issue is prized for its sleek design symbolizing modern architecture and technological optimism. It also serves as a fascinating example of international recognition of U.S. world fairs by foreign postal authorities — a rare and desirable thematic for collectors of both Expositions and Architecture stamps.
