This U.S. commemorative stamp was issued in 1962 to celebrate the Seattle World's Fair, officially known as the Century 21 Exposition. It features a striking illustration of the futuristic Space Needle alongside the monorail, both icons of the fair’s “world of tomorrow” theme. The vertical layout, deep blue gradient, and bold red typography capture the spirit of modernism and innovation. The fair emphasized space exploration, science, and progress during the Cold War era. A must-have for collectors of world fair and U.S. history themes.
