A classic early-Republic Macau postage due stamp featuring the ornate “PORTEADOR / RECEBER” frame printed in deep green, with the ½ avo denomination in bold black. This issue is distinguished by its striking diagonal red “REPÚBLICA” overprint, applied after the 1910 Portuguese revolution to reflect the new political order. The design’s lush scrollwork and balanced typography remain hallmarks of Macau’s early fiscal/postage due issues. Highly collectible for specialists in Portuguese colonies, overprint varieties, and early 20th-century transitional postal markings. Well-struck overprints like this example are always in strong demand.
