Issued by Mexico in 1962, this commemorative stamp celebrates the Seattle World’s Fair (Century 21 Exposition) held in the United States. The design prominently features the futuristic Space Needle, the iconic observation tower constructed for the fair and symbolizing technological progress and the space-age optimism of the early 1960s. The stylized beams and geometric patterns around the tower reflect the era’s fascination with science, innovation, and global cooperation. Stamps related to international exhibitions are popular among thematic collectors of world fairs, architecture, and space-age design, making this issue a distinctive addition to a mid-20th-century collection.
