southtyrolean, who seems to take an interest in found graffiti posted this one (from Graz)to his Flickr stream, describing it:
in the Sackstraße, near Kastner&Öhler (entrance to the car park for bikes) :: in der Sackstraße, neben Kastner&Öhler (Eingang zum Fahrrad-Abstellplatz)
I especially like this one.
