Got burned on a Cadillac sign like this 2 years ago on eBay. They look great in pictures, but get them up close and even a novice could tell the difference. Uneven spacing of letters, lines and edges aren't straight, and the tell-tale aging like knocking the porcelain off only around the edges. Oh yes and the backs are always slick white. eBay is being inundated with fakes. Not even worth fooling with them now. Unless I knew the seller and it's a reputable seller, I wouldn't touch it. IMO, some fakes (well marked that is) are ok for restored gas pumps, etc, but these other guys trying to pass them off as legit, then they are nothing but charlatans. And no dealer signs like this came from over there. We made everything here then.
