Fully licensed Ed Roth Green Rat Fink metal sign. Terrific automotive decor. Great for modelers. A custom car builder, Roth was key in the hot rod movement of the 1960s. Roth is best known for his caricatures, typified by Rat Fink, depicting imaginative monsters driving replicas of the hot rods he and other rodders built. Also known for his innovative work in turning hot rodding from backyard engineering where performance was the bottom line into a refined art form where aesthetics were just as important, utilizing new materials such as Fiberglass bodywork.
