I don't see how anyone would know if its fake or not unless they had a book saying they only did porcelain signs.. I see many are for sale for thousands and they are not porcelain. If this was a fake repo there would be a whole lot more than 2 of them ever seen before on ebay (worthpoint reference) and the marking of the company name is spot on. I have never seen a repo of this dimensions before either. Who the hell knows but you are just guessing it seems like to me.
