There seems to be enormous variation in nameplate color and placement.
My '57 Bubble from CA is pale blue but the location is directly below
the rear window. By the way, an energetic helper "polishing",
obliterated most of the nice pale blue and guess what, it's grey
underneath. After all those years, it's hard to imagine that the "blue"
of various hues hasn't been altered by weathering, polishing, birddoo,
etc.
