This classic 1 centavo black stamp from Paraguay was issued in 1892 to commemorate the Universal Postal Union (UPU). The design features a radiant central star, a national emblem symbolizing hope and unity, surrounded by laurel and palm branches. Above, the inscription reads “República del Paraguay”, while below it proudly acknowledges the “Unión Postal Universal”. Printed in a sharp black shade, this issue reflects Paraguay’s early commitment to global postal communication. A fine example of late 19th-century South American philately, highly sought after by collectors of classic issues.
