This Portuguese stamp belongs to the iconic "Ceres" definitive series, first issued after the establishment of the Republic in 1910. The design features Ceres, the Roman goddess of agriculture and fertility, symbolizing prosperity and abundance under the new Republic. The inscription reads "REPVUBLICA PORTVGUESA", with the denomination 5 Centavos. Printed in brown, it was part of a wide range of values that circulated extensively during the early decades of the Portuguese Republic. Highly collected, the Ceres series is celebrated for its elegant engraving and historical significance in Portuguese philately.
