This striking 20-pfennig West Berlin semi-postal–style public welfare issue promotes workplace safety, featuring a bold graphic of a hand above a circular saw. Issued by Deutsche Bundespost Berlin, it reflects the early 1970s design trend of minimalist, line-art industrial iconography. The vivid purple engraving stands out for its clarity and strong visual message: “Jederzeit Sicherheit” (“Safety at All Times”). A desirable thematic item for collectors of labor, industry, public awareness campaigns, and modernist German design. Clean impressions and well-centered examples are especially sought after.
