Orange Crush Sign...can someone tell me about it?

Hi Everyone, I recently unearthed this sign while renovating my store. It was a corner store built at the turn of the century and the sign was covering a hole in the wall under some old paneling.
The sign measures 35" x 36" and is enamel coated tin, self framed with folded edges and has embossed lettering. There is minimal damage (the pic of the top left corner shows the worst) and there is no rust.
I would greatly appreciate any knowledge you might share on it's age and value.
Thanks very much, Sharon
