Taps & Moses have been two of the most prolific graffiti writers in Europe for years. More recently, between 2008 to 2010, using their collective moniker 'Topsprayer', they painted 1000 trains in 1000 days. It's not only the volume of production for which they're known, but the quality of their work. In addition to an astounding variety of pieces executed in known graffiti forms, some very unusual productions are featured in the book.
