Action Painting: Bringing Art To The Trains (Softcover)All works presented in this book no longer exist. Gone for good, washed off the sides of the trains, sometimes only hours after they were first created. Often what remains is just one photo, a final remnant of something that took a great deal of skill, courage, and determination to create. The authors of Action Painting present the most comprehensive collection of art ever created on Europe's transit systems, including highlights of the past 25 years.
