Issued by Deutsche Bundespost in 1971, this striking graphic-design stamp promotes road safety awareness, part of Germany’s public safety campaign series. The bold blue line-art shows a car, a ball, and raised hands—symbolizing caution, especially around children playing near traffic. Its minimalist, modernist style reflects early 1970s German design trends. A popular thematic issue for collectors of public awareness, transportation, and social responsibility topics. Clean examples remain sought after due to the series’ distinctive visual identity.
