I emailed the seller the first time it was on ebay and told him it was a reproduction. I never got a response. This seller is pretty close to me but I don't know him. I don't know a lot about Ford signs, but I do know they should be marked Veribrite. Also, the letters just don't look right. Compare them to a real sign and you can see what I mean.

The Humble sign that tx_oil was questioning was for a bulk tank I think. There are also Humble Dealer signs in red.
