The prices at the Pure Evil show seemed dementedly high for such a new artist (to gallery's at least) so I'd be interested to hear how they are selling too. I know if I was looking to drop £6000 on a roughly painted animial on some doors I'd want to be pretty sure there wasn't going to be a bunch more released in a few weeks.
i hear you about saturation as we are all pretty much internationally buying art consumers here, but i do think that the shows have been pretty widely dispersed, which is good for people who want the opportunity to view the art. i thought his piece on curtain road - the big shutter with the rabbit - was conceptually one of the most impressive pieces of work i've seen on the streets of london in a long time. roa seems to be using the opportunity afforded by his gallery shows to knock out some great outdoor work whilst he is on his travels. the prices at pure evil were higher than i expected too though, and the pieces were generally very large. i think he limited his buying public with the medium for that show somewhat.... not too many people have space for a set of industrial lockers in their house.
