Over the time during my visits to Düsseldorf I found some pieces of an unkown writer or a crew with an unique signnature. The pieces were always cup cakes; the first I found in Derendorf S in 2014, and I found more everywhere on the tracks or near the tracks, not always easily accessible. I felt amused and speculated, who could be responsible for it. Because of the pink and light colours, I speculated the writer may be a girl or a crew of girls. As I could get no information on it, I stopped thinking and just have fun with those cup cakes. Later I have found in D-Völklinger Straße the name of the writer/crew. If I am right, the crew’s name is CAKE.
