Well, I just learned that they now fake this item. It is not real.

3 sellers, all with almost the same Ebay name, all near Chatanooga, TN, are selling this sign. When compared to a known good one, it is clear that the font is wrong on the permit number, letter spacing is wrong, hole size on the grommets are wrong, the stamp in the center is wrong....

I've attached pics of a real one for comparison.
