Is this sign a fake? The current offerings similar to this sign on eBay have the flange bent the opposite direction but otherwise look the same to me. I don't know signs well enough to explain what the finish is. It's not porcelain. Maybe a baked on paint or decal...? Any input...?

IMO- the one shown above and the link below are both aftermarket models with a right & left hand flange..
there is an orig. porcelain flange firestone tire &
there are aftermarket models of the same with the flange's
black on the aftermarket & white on the originals ...
