装饰格栅 - 1970-1980 - 带有俄文文本的原版大型苏联金属工业安全标志：

危险。禁止在手柄上装有松动头部的工具时作业。\n（“Danger. It is forbidden to work with a loose tool head on the handle.”）\nUSSR，约1970年代–1980年代。\n大约尺寸：40 × 50 cm。\nOriginal period sign in good vintage condition. Large and highly decorative, with striking red-and-black Soviet industrial graphics.\nThe illustration clearly shows the danger of a loose hammer head flying off during work.\nToday, the image also gives the sign a humorous character:\n“Secure the hammer — or it may fly straight at your head！”\nA great decorative piece for a workshop, garage, man cave or industrial-style interior.
