It seemed very appropriate to photograph a Stasi office with the Polaroid, and sure enough you get all the pre-digital gloom and authority of the Stasi’s former HQ in this shot. They have kept one floor almost exactly as it was after the fall of the wall in 1989 - which is almost exactly what it was like in 1960. Another room full of hidden cameras in it is a boys’ paradise – cameras in buttons, watering cans and even logs. You can even sit and have a coffee in the Stasi canteen on the way out, like the cold war never ended.
