This 9-cent stamp from the Australian Antarctic Territory features a striking illustration of the Leopard Seal, one of Antarctica’s top marine predators. Rendered by artist G. Browning, the design shows the seal gliding through icy waters surrounded by vivid red and yellow fish, highlighting the region’s rich marine ecosystem. Issued during the mid-1960s wildlife definitive period, the stamp is valued by collectors for its bold color palette, classic recess-engraved finish, and its place within early AAT natural history themes. Cleanly printed and finely perforated, it remains a favorite among Antarctic topical collectors.
