For several years, urban artist Tristan Eaton maintained a studio at 158 Roebling in the Williamsburg section of Brooklyn. Although he’s long-gone from that space, he still curates or paints the walls there. This year, he invited graffiti twins HOW and NOSM, as well as Cyrcle, to create an eye-popping mural that stretches around the block. They succeeded. (Photos: Aymann Ismail/ANIMALNewYork)
