23. Meggs

Meggs, and his Everfresh Crew, haven't sat on their laurels in 2012. Back in June, we noted an impressive showing in Hong Kong and terrific work at Pow Wow in Hawaii. Meggs has since shown at San Francisco's White Walls and rounded out the year crushing it down in Miami. 

A traveling man, this Australian graffiti writer hasn't stopped pushing since January 1, 2012. Shout outs are due to Rone and Phibs too.
