Spain 1930 Francisco Pizarro 5 Cents Postage Stamp

This is a vintage Spanish postage stamp issued circa 1930 as part of the Spanish American Union series. The stamp is printed in a sepia or reddish-brown monochromatic ink on off-white paper and depicts the conquistador Francisco Pizarro on horseback. To the top right, the denomination '5 CTS' is visible next to the country name 'ESPAÑA', with 'CORREOS' appearing at the bottom right. The design utilizes a fine-line engraving style characteristic of early 20th-century philatelic production, showcasing detailed cross-hatching and shading on the figure, horse, and rugged landscape. The stamp features standard comb perforations on all four sides. Regarding condition, the perforations appear largely intact, though there is a slight rounding on the top right corner. The centering is moderately off to the left, which is common for this era of production. There is no visible postmark (canceled by pen or stamp), suggesting it is in unused or 'mint' condition, though the state of the gum on the reverse side cannot be determined from this view. The paper exhibits a mild natural patina consistent with its age of nearly a century. This item represents a period of Spanish philately focused on historical commemorations and explorer themes.
