An Enamel Sign is a metal advertising or informational sign coated with vitreous enamel to produce a colourful, weather-resistant surface. Widely used from the late nineteenth century onwards, enamel signs advertised products, businesses, petrol companies and public services. Antique examples are highly sought after by collectors for their bold graphics and historical interest. *Related Terms*\ Advertising Antiques, Petroliana, Signage, Vintage Advertising, Wall Sign.
