Los Angeles Graffiti artist RETNA (of the world famous Seventh Letter crew) has always blurred the line between street art and fine art, dexterously "altering" billboards and other advertisements or patterning his Old English-inspired script. The visionary's solo exhibition, "RETNA: The Hallelujah World Tour New York," makes its New York debut with a big Fashion Week party on February 10th, which is being presented by Vladimir Restoin Roitfeld (son of former French Vogue editor Carine Roitfeld) and Andy Valmorbida. The two jet-setting art dealers have been long supporters of graffiti, and in the past have supported such artists as Richard Hambleton, who PAPER once dubbed "The godfather of street art." Retna has created 35 works for the exhibit, which will be held at SoHo's 560 Washington Street gallery, and is curated by RVCA owner Pat Tenore.
