A striking set of nine vintage enamel number plaques originating from Czechoslovakia, circa 1950s. Each plaque features a bold white numeral (1 through 9) against a rich cobalt blue background, framed by a classic white border. Made from durable enamel-coated metal, these pieces were originally used as house numbers and reflect the utilitarian charm of mid-century Eastern European design. All nine plaques are in excellent vintage condition, showing minor wear and a light patina consistent with age, adding to their authentic character. Each plaque has pre-drilled holes, allowing for easy installation or creative display. Perfect as an industrial wall art set, design accent, or collector's item celebrating timeless typography and vintage aesthetics.
