Artnet.com is having an online urban art auction, which began July 7^th and runs through July 23^rd. The catalogue contains works by many of the major names in the scene, from the 80s through today, such as Dondi, Crash, Haring, Basquiat, Barry McGee, Banksy, Nick Walker, Faile and Shepard Fairey. There are also some strange, albeit nice, inclusions such as Mr. and Jim Houser, as well as some weaker urban choices, but on the whole this auction is definitely worth checking out as there is a good range of pieces in it.
