"There was no special event that made me decide. I had collected some photos and the idea was in the back of my mind for a long time. It was growing and growing, so finally I said, 'I must paint this.' I come from East Germany and am not a Marxist, so of course at the time I had no sympathy for the ideas, or for the ideology that these people represented. I couldn't understand, but I was still impressed. Like everyone, I was touched. It was an exceptional moment for Germany."
