I once caused a ruckus on Slog by typing the phrase "pro-graffiti." Sweet Jesus, you'd think I'd said I was "pro-rape." Artists like GHOST are why I'm pro. GHOST was one of the originals, in late 1970s, pre-Giuliani New York, painting all those trains belonging to the NYC subway. And while the days of sneaking into train yards are gone forever (replaced by legal big-money pieces, commissioned by legit big-money corporate sponsors), GHOST remains one talented sonofabitch.
