Spain 1931 Second Republic Nicolás Salmerón 50 Centimos Postage Stamp

This is a blue-toned postage stamp from the Second Spanish Republic, issued circa 1931-1932. It features a portrait of Nicolás Salmerón, who served as a President of the First Spanish Republic. The stamp is printed on paper with a perforated edge typical of standard postal issues from the early 20th century. The central design is an engraved-style portrait of Salmerón with his name inscribed below. The top of the frame reads REPUBLICA ESPANOLA, while the bottom denotes the denomination as 50 CORREOS. The very bottom margin mentions FNMT (Fabrica Nacional de Moneda y Timbre), the Spanish national mint and stamp printer. In terms of condition, the stamp shows a heavy black circular date stamp (CDS) or postal cancellation, which obscures the upper right quadrant of the image and the word CORREOS. The perforations are somewhat uneven, with a significant 'short perf' or tear at the bottom right corner and some minor toning (yellowing) visible along the top edge, suggesting oxidation of the paper or adhesive over time. The portrait itself is well-executed with fine line work and shading, indicative of the quality engraving standards of the period. The centering of the image is slightly shifted toward the bottom left side of the paper within the perforations.
