As I always say: The most interesting details of a city are not on the ground floor. E.g. this penguin seen on a balcony rail of a building in Vienna. I was told, the creator of this penguin, which had been used for a campaign by the Austrian tourism board, has put this figure on his balcony.
The number of the penguins are changing. Sometimes there is only one, sometimes there are even more of them to see. By the way in summer 2012 another animal got famous in Vienna: The bear near the station Gumpendorfer Strasse.
