Talking of special plates reminds me that the special 1967 licence plates issued in Quebec featured different front and rear plate designs.The ones intended for the front had EXPO 67 writ large and the actual licece plate number much smaller. Urban legend had it that the first Quebecker to venture into Maine in 1967 got a parking ticket made out to licence tada tada... you got it!
