I had a question about a curb sign I've found. It's a quaker state and has been painted over and used as another sign. I was talking to the fellow that had it and he had used it as a barricade and thats why it had been painted. I flaked off some of the paint where it was peeling, and saw the green under it but some of the green came off as well and it was green paint and not porcelain chips. so I diddnt get it and my question is were these green tombstone signs all porcelain or were there painted varieties as well?
