In february 2011 the club museum of Hamburger SV opened a new temporary exhibition about the HSV fan culture named: "Wir stehen Schlange vor dem Stadion – Die Geschichte der HSV-Fans“. (We're standing in line in front of the stadium - the history of the HSV fans)
The exhibition follows the development of fan culture from the Empire period up til present day, describing the various dimensions of being a HSV fan.
There are video documentaries with interviews of fans from the 1920's and presentations of fan groups world wide.
Visitors get a chance to experience the supporter terrace of the HSV arena in a replica of the Fantribüne.
Social aspects and football-related violence are two other themes of the exhibition which seems to be well worth a visit.
The exhibition will run until spring next year, so there's plenty of time.

The HSV Museum is located in the HSV Arena in Hamburg. It changes names quite often. When I was there it was called 'Nordbank Arena' but it is 'Imtech Arena' but I feel that it would be all right to just call it 'Volkparkstadion'. In the UEFA context it is simply called "Hamburg Arena".
