Herlitz pbs AG

Finding Herlitz's head office proves futile. The address I have for this distributor of paper products take me about a half dozen miles from Alexanderplatz into the former East German part of the city. The building turns out to be a totally trashed, falling apart structure and looks like it's been that way for years. It doesn't make any sense because when you look in the phone book for the company's address-this is the address it shows. Thinking I'm mistaken I ask a passing police officer if this is "Berliner Strasse 27". Yes it is.
