12. Retna

If you've been paying attention you may have noticed that Retna has been a favorite of ours for a while now, including his ranking in the Top 25 Artists lists of 2010 and 2011. In 2012 he shifted into auto-pilot and reminded us just how amazing he is, from the Vegas Metropolitan Hotel and the gallery walls of Known Gallery in LA in February, to the Bowery Mural Wall and walls in the Bronx in March, down to Mexico's Art Careyes Gallery for the Time Travelers exhibit in April, and rounding out the year with work at Michael Kohn Gallery and a collaboration with Louis Vuitton for good measure.

Oh yeah, we can't forget the artist's recognition by MoCa making the list of The 10 Biggest Graffiti Moments of November 2012. We gave Retna a nod for Complex's Man of Next Year in Art & Design for a reason.
