A vintage postage stamp featuring a realistic Tyrannosaurus rex in profile, roaring with mouth open. The dinosaur is illustrated in engraved style, using muted olive green, ochre, and brownish tones. The background contains stylized prehistoric ferns and cliffs in faded ink colors. The stamp is framed by a classic ornate border in burgundy red, with perforated edges. The paper looks visibly aged yellowed and stained, with realistic dirt smudges, edge wear, minor creases, and ink misregistration typical of early 20th-century printing. No text or numbers. Isolated on solid black background, high-resolution, print-ready.
