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. This sign measures 26.5 inch across and 23.25 inch tall Thanks for looking. Let me know if you need sooner.
