While worldwide crackdowns on graffiti are coming down hard and fast, 10.Deep together with Sasha Jenkins and artist Chino BYI have taken a trip down memory lane in remembering the past in a compilation of sketches from some of the world’s most critically acclaimed artists. The book, Piecebook: The Secret Drawings of Graffiti Writers will also feature sketches on display starting Thursday, June 12th at a special gallery showing accompanying the book’s release. A special event book package will be on sale featuring a copy of the book alongside a special t-shirt and sharpie with a further online release set to take place at 10.Deep on Friday at 12:00 pm New York time.
