For your consideration, here is a 1968 Continental Mark III National Press Preview Metal Part, dated February, 12th, 1968. I am not sure exactly what this was used for. Maybe part of a press pass badge or a car show exhibit. There are two wires on the reverse side. It measures 2 by 2 3/4 inches. It has some wear and scratch marks on it. Item pictured is the actual item up for sale and comes from a non-smoking household. (123.149v-.6ob)
