Vintage High Voltage Enamel Sign, Bulgarian Factory Warning

A striking vintage triangular porcelain enamel warning sign manufactured in Communist Bulgaria in 1976 for factories and other industrial premises.

The pictogram warns of high voltage and potentially dangerous electrical current in the ground. The sign is made from pressed sheet metal coated with yellow, black, and red porcelain enamel.

This unused piece comes from old stock and remains in superb vintage condition, with only minimal traces from age and storage. It would make a distinctive industrial decoration or an interesting addition to a collection of vintage safety signs and Communist-era design.

Dimensions: each side measures 31 cm / 12.2 in.
