I think even my basic grasp of french can tell me that what's written on this sign is Rhine and Danube! Apart from that, I have no idea where it originated. I have been told it might be railway related although I could find no information on the internet to substantiate this.
Anyway, it's not an unattractive thing and is enamelled on a hefty piece of metal.
There is some rust on the back and a couple of small areas of wear on the enamel but overall in great condition.
