This 25-cent Australian postage stamp celebrates the nation’s world-famous wool industry, one of the pillars of its agricultural economy. The design features a Merino ewe with her lamb in the foreground and a ram above — a nod to selective breeding that made Australian Merino wool prized for its fineness. The muted grey background and minimal text emphasize the purity and quality of the fiber. Issued in 1970 as part of the “Primary Industries” definitive series, it honors Australia’s pastoral heritage and its vital contribution to global textile trade.
