Soviet Enamel Warning Sign – “STOP! HIGH VOLTAGE!” Original Soviet-era enamel warning sign with Russian text “СТОЙ! ВЫСОКОЕ НАПРЯЖЕНИЕ!”, translated as “Stop! High Voltage!”. This type of sign was used at electrical substations, industrial sites, factories, and infrastructure facilities across the USSR, including the Estonian SSR. • Material: steel with vitreous enamel coating • Dimensions: approximately 28 × 21 cm • Country of origin: USSR (Soviet Union) • Period: circa 1960s–1980s The sign features a classic Soviet industrial design with strong contrast colors (red, white, and black) and a lightning bolt symbol, intended to provide a clear and immediate safety warning. Such signs were produced for functional use rather than decoration, which contributes to their authentic utilitarian character. Condition: The sign is in good vintage condition, showing normal signs of age and use. There are minor enamel losses, scratches, and light oxidation, particularly around the edges and mounting holes. The lettering remains clearly legible and the enamel surface is largely intact. Overall wear is consistent with prolonged industrial use and enhances the historical and collectible value of the piece. Collectability: Original Soviet enamel warning signs are increasingly sought after by collectors of industrial design, Soviet memorabilia, and vintage signage. Due to their durability and graphic quality, they are also popular as decorative objects in industrial or loft-style interiors. This is an original period item, not a reproduction.
