Street art academic Daniel Feral recently released his “Feral Diagram 2.0,” an infographic that seeks to map all the connections between graffiti and street art’s divergent micro-genres, from original late-60s writers through the “beautiful losers” of the’90s to the “rurbanism” and “urban avant” of today. The piece is a follow up to Feral’s first “Feral Diagram,” which was released last year. “Feral Diagram 2.0” is available for purchase here.
