"The police in and around Frankfurt have photographed everything and they have kept record of everything for an entire era — from 1973 to 1985. Red flags, squatters, kidnappings, bank robberies, rallies, the fight against the western runway at Frankfurt Airport, the world view." — Annette Ramelsberger. At the initiative of the artist Jochem Hendricks, the photographer Magdalena Kopp has for more than five years sorted out this police archive to create the book Revolutionäres Archiv.
