Thanks for looking at our auction. . If your not happy with any purchase please return it before leaving negative feedback as we are a new seller and need positive feedback. Our signs are made using commercial grade sign material which is 1/8 inch thick dibond material which is aluminum skins with a pvc middle. Very durable and can be used outdoors. These are not cheap tin. We create the signs to look like originals from the era and hand age them to give them that barn find look. We have a process that makes real rust so the aging is real and not paint. The signs are then cleared so give them a protective layer so they will last. Please email any questions or have a special sign you want made and we can do that too. This sign is 4 inch by 16 inch. Thanks for looking.
