[Bernard Marx]

That's interesting. I guess it depends on where you come from. The originals in my area were tiny little things you could read at slow speeds. You usually found them on roads that had been turned into secondaries by construction of newer ones.

I've seen them on little roads and I've seen them on not so " little " roads. They were still around well into the 1960's and in some places, after that. Yes, it all depends on what part of the country one was driving through. :-)
