The Vintage Shell Sign is a rare and original piece of transportation advertising collectable for the 1930's Please study the pictures carefully including the specific curvature of the sign and the patina on the back. Please satisfy yourself on that basis and do research on the replicas obvious by the flat nature of the signs and fresh enamel or usually just paint on the back that hasn't suffered from almost 100 years of oxidisation before purchasing.
