Found some Shots of the original one, I thought you wanted to preserve it as much original as possible? :D

I would prefer the yellow ones (^^ have to think of the before yellow and now white stripes on motorways):

Nearly the whole dialog compared with the new German ones are on this site (scroll down):

If I would prefer the old ones with the buggy translation? I don't know. But yellow I would prefer personally.

And 'Hierauf'....hmmmm 'Darauf' is better for sure... it sounds otherwise to overblown....

I hope you agree :).

And before I forget it... PLEASE REMOVE THE NEW GERMAN ORTOGRAPHY!
