20. ROA

One word to describe ROA's presence in 2012 would be global. It would almost be easier to name the places he hasn't been. Murals began popping up in places like Belgium, Stockholm, Mexico, Arizona, Australia, Johannesburg (which we proclaimed his best work ever), and the County of Kings, Brooklyn. ROA's graphic style—detailed anatomical drawings of native animals—is among the most recognizable, and we mean that in the best possible way.

With many muralists once you've seen their work...well, you've seen their work. ROA manages to make every mural fresh and unique without sacrificing the aesthetic that we all love. We hope he doesn't rest until there is a ROA mural up in every city.
