We have an  Automotive Rubber Stamp Vintage item.  The stamp is marked on top "Automotive Wares Inc. Rocky Hill Conn." and the rubber stamp reads "The information you see on the window form for this vehicle is part of this contract information on the window form overrides any contrary provisions in the contract of the sale".  It appears in good shape.  It measures about 2 1/2" in H x about 3 1/2" in w x about 3/4" in d.
