Just this week we noted how Poster Boy was stepping up his game and true to form, he’s now even collaborating with other artists. Plus he’s not only hitting the subway advertisements, but now also posting stuff up inside the actual subways too. His latest collection of work was done in partnership with Aakash Nihalani, an artist we spotted outside NYU’s Barney Building back in May that uses neon colored tape to create 3D-ish shapes. Click below for a sampling of the new underground images.
