10 Centavos Postal Stamp featuring a historical figure

This item is a postage stamp, likely from a Latin American country given the 'CENTAVOS' denomination. The stamp is predominantly blue in color with white or very light blue details and text, printed on what appears to be standard stamp paper. It features a central oval vignette depicting the bust of a historical male figure, possibly a military leader or dignitary, dressed in a uniform with what appears to be a high collar and epaulets. The figure has dark, curly hair and an intense gaze, though the resolution of the image makes precise identification challenging. The portrait is framed by an ornate oval border. Above the portrait, text is visible, possibly indicating the issuing authority or country, though it is too blurry to decipher definitively. There are two stars, one on each side, above the central oval. Below the portrait, the denomination '10 CENTAVOS' is clearly visible in an ornate cartouche. The number '10' is also present in the bottom left and bottom right corners of the stamp. The stamp exhibits a perforated edge, indicating it was separated from a sheet of similar stamps. The visible part of the stamp shows some blurring, suggesting either the original printing quality or movement during photography. There are no obvious tears or major damage visible, but the exact condition of the perforations and gum (if present) cannot be assessed from the image. The style suggests it could be from the late 19th or early 20th century, a common period for detailed engraved portraits on stamps. The overall impression is one of a used or previously collected stamp that has been handled.
