Our signs are made using commercial grade sign. Material which is 1/8 inch thick dibond material which is aluminum skins. Very durable and can be used outdoors. We create the signs to look like originals from the era.
And hand age them to give them that barn find look. That makes real rust so the aging is real and not paint. Then cleared so give them a protective layer so they will last. This sign is a nice large sign and is 36 inch tall. If you need it sooner let me know and I will make it faster.
I work full time elsewhere and do signs on the side and sometimes get behind.
