Esso - Enamel sign - 50x40cm - Made of thick steel sheet and enamel

Enamel signs like this Esso example are vintage advertising collectibles made from steel sheets coated with durable enamel. Introduced in the early 20th century, these signs were widely used by companies to promote their brands outdoors, especially gas stations and service centers. The thick steel base ensures sturdiness, while the enamel coating offers glossy, weather-resistant protection, preserving vibrant colors and sharp graphics. Esso, a well-known international oil and gas brand, used such signage extensively during the mid-1900s; today, these signs evoke nostalgia and are prized by collectors of petroliana for their artistic and historical value. Measuring 50 by 40 centimeters, this sign represents a classic format that was both visible and practical for roadside advertising. Beyond advertising, enamel signs are valued as decorative art pieces that capture the industrial and commercial spirit of their era.
