This is a Paraguayan official postage stamp issued in the early 20th century, featuring the national emblem with radiating star and laurel wreath. Printed in violet, the design includes the inscription REPÚBLICA DEL PARAGUAY at the top and U.P.U. (Universal Postal Union) to the right. The bold red overprint “OFICIAL” designates it for government and administrative use only, making it distinct from regular postal issues. Denominated at 50 centavos, this overprinted issue is a notable piece for collectors of official mail, UPU commemoratives, and Latin American philately. Its crisp typography and dual-color presentation enhance its historical and aesthetic appeal.
