There has been a spate of posters for local Berlin beer companies recently which have been playing the home card and featuring Berlin in different ways. Berliner Pilsner has based its entire campaign on differing attitudes and sensibilities in different parts of the city.
Hopefully you should be able to tell that Friedrichshain is where the young trendy people hang out (i.e. not me!)
Another beer company Schultheiss which is also local has decided to just talk about Berlin in total. Their original line is a play on words: "Berlin ist wieder fluessig" which either means Berlin is liquid again i.e. Berlin has got something to drink again or it means Berlin has money again (which it clearly doesn't) so either way they are talking about something which is close to the hearts of many Berliners.
But this being Berlin, you will always see a certain anarchic tendency coupled when done best with wit, as demonstrated by this redesigned poster which I saw on Yorckstrasse.
So there you go. Berlin's beer advertising at its best!
PS. I seem to have now fully recovered from a year of working very hard and should be posting more soon.
