Scrolling through this website and looking at pics of this 1967 Corvette and came upon the NCRS validation of the window sticker and tank sticker. The window sticker is a reproduction document and should not have been validated: An excerpt from the ad: "Original NCRS validated Window sticker- Thinking about how special this is due to the fact that this piece of paper was adhered to the inside of the drivers window with water soluble adhesive. The dealer was mandated by Federal law to leave it on the car and not remove it. That meant the new owner either tore it off upon leaving the dealer as it obstructed the view or in the case of this car it was carefully removed by the original owner and securely stored. It has been authenticated by the NCRS as the genuine article"
