This striking 10-pfennig stamp from the German Democratic Republic honors Clara Zetkin (1857–1933), a leading socialist, women’s rights activist, and co-founder of International Women’s Day. Issued in deep green with a bold red carnation, the design features a strong portrait of Zetkin, symbolizing her lifelong advocacy for equality and workers’ rights. A classic mid-20th-century DDR commemorative, it remains a meaningful addition for collectors of political history, prominent women, and German philately. Well-engraved and typical of the era’s minimalist yet impactful design style.
