Street artist RETNA has been busy as of late. Following on from his recent takeover of the Graffiti wall at Bowery and Houston, the artist has hooked up with graffiti legend Cope2 to work on a piece which sees both artists employing their signature styles. The collaboration took them to Cope2′s home of the Bronx, where RETNA’s glyphs sit harmoniously next to the former’s bubble script. Let’s hope this is an indication of projects to come between the two artists.
