Republica Argentina 15 Centavos 'Ganadería' Postage Stamp

This is a vintage postage stamp from 'Republica Argentina,' featuring a prominent central image of a bull's head, likely symbolizing 'Ganadería' or livestock/cattle farming, which is also visible as text on the stamp. The stamp is primarily dark blue or indigo in color, printed on light, possibly off-white or yellowish paper. The bull's head is depicted in profile, facing right, encircled by a decorative border with swirling motifs on the upper right and left. Above the bull's head, the words 'REPUBLICA ARGENTINA' are clearly visible in an arching banner. Below the central image, the denomination '15 CENTAVOS' is displayed, with '15' in larger type on both the bottom left and bottom right corners, within rectangular boxes. The word 'GANADERIA' is horizontally inscribed beneath the bull's chin, cutting through the lower part of the circular frame. The stamp appears to be perforated along all four edges, indicating it was part of a larger sheet. The perforations show some wear and slight irregularities, particularly along the top edge, suggesting it was separated from other stamps. There is a prominent circular cancellation mark heavily obscuring parts of the bull's head and the surrounding text, especially on the right side and lower left, indicating it has been used. The paper shows some discoloration and minor foxing consistent with age, and the corners appear slightly rounded. The printing quality, despite the cancellation, suggests fine line engraving, a common and precise method for stamp production of its era. Based on the style and text, it likely dates from the early to mid-20th century.
