Wills Woodbine Vintage Enamel Advertising Sign. The enamel sign has black high lighted letters on a racing green background. The metalwork is complete, one corner is bent at the tip. The sign has heavy rust as well as loss of enamel, fortunately not so much in the text area. The enamel sign is 91.5 cm (36 inches) wide and 61 cm (24 inches) tall.
