Steel Tattoos by Won aka New

Won aka New made a series of great Trainworks in early 90s on munich S-train. His "Steel Tattoos" been published in books like "Graffiti Munich" or "Action Painting". He is a pioneer in painting on trains in non writing context and for sure these works are one of my favorite works on trains.
