This classic 1 Centavo stamp from Paraguay, issued in 1892, commemorates the nation’s membership in the Universal Postal Union (UPU). Printed in a rich brown shade, the design features the Paraguayan national emblem with a radiant star encircled by a wreath, symbolizing unity and sovereignty. The bold numeral “1” is centrally placed within an ornate oval frame, with “UNION POSTAL UNIVERSAL” inscribed along the sides. A fine example of 19th-century Paraguayan philately, it represents both postal reform and national pride. Highly collectible for its age, design, and historical significance.
