Spain 1931 Republica Española 5 Cents Stamp featuring Pablo Iglesias

This is a physical postage stamp from the Second Spanish Republic era, specifically the 1931 definitive series. The stamp depicts a profile portrait of Pablo Iglesias Posse, the founder of the Spanish Socialist Workers' Party (PSOE). It is printed in a dark brown or sepia ink on cream-colored paper. The design features 'CORREOS' across the top and 'REPUBLICA ESPAÑOLA' at the bottom, with the denomination '5 CENTS' located in a circular medallion in the bottom right corner. The stamp shows evidence of a circular black ink postmark or cancellation mark across the center of the portrait, indicating it was used for mailing. The perforations are present on all four sides, though they appear somewhat irregular or 'fuzzy' along the top edge, suggesting a slightly rough separation from the original sheet. There is a visible manufacturing imprint at the very bottom edge reading 'F.N.M.T.', which stands for Fábrica Nacional de Moneda y Timbre, the Spanish Royal Mint. The overall condition shows signs of aging with minor foxing or darkening of the paper, particularly along the edges. The centering of the image within the perforations is slightly shifted toward the top left. This piece is a significant philatelic artifact from a transformative period in Spanish political history.
