Argentine Republic 5 Centavos Stamp, 1915 issue, with Postmark

This is a rectangular postage stamp from the Argentine Republic, featuring a primary color scheme of red or reddish-brown, with white or light-colored text and design elements. The stamp is perforated around its edges, indicating it was separated from a sheet. The central image appears to be a portrait or bust, likely of a significant national figure, though details are obscured by a heavy, dark postmark. The top border of the stamp clearly shows 'REPUBLICA ARGEN...' (likely 'REPUBLICA ARGENTINA'). The lower portion of the stamp displays '5 CENTAVOS' in white text, with the number '5' prominently featured in the bottom left and bottom right corners. An additional numeric marking, '1915', is visible near the bottom center, which suggests the year of issue or a significant date. The most striking feature is the black, circular postmark covering a significant portion of the stamp's face, making the central design difficult to discern. The postmark includes what appears to be a date 'T. P. M.' (possibly indicating a postal transit mark) and a series of numbers and letters, although they are not fully legible. The stamp shows signs of use, typical for a canceled postage stamp, including the postmark and some slight discoloration or paper aging. The edges of the perforations appear somewhat softened, possibly indicating wear or handling over time. The overall condition suggests that it is a genuine, used stamp, with the postmark adding historical context to its usage rather than being a defect per se. The quality of the printing appears consistent with early 20th-century philately, with a relatively clear and well-defined impression despite the heavy cancellation.
