Like I've said before placement is the key to winning at auction.

Think about it where would you rather sell your Banksy? In a sale dedicated to the artist, which will have all the houses advertising spend dedicated toward promoting one artist and therefore attracting all the Banksy collectors and people looking for his work.

Or in a multi artist sale, where they are amongst 100+ other things, more often than not which have nothing to do with Banksy, that they auction house is also desperate to promote and sell?

I'm not saying the Bonham's sale is bad, far from it there is some cracking things in that sale, but I'd always favour a theme sale to a general one.

breezied is correct, Forum have had some stellar Banksy results over the past year - that is for a reason, they actively promote themselves as the go to auction house for Banksy editions, and for collectors who are not on the forums and so forth they look to who has the name for selling a particular artist, it's a clever strategy, and clearly it works. Sotheby's London do the same with Warhol prints, and have done for the past 15 years, their results are considerably better than others for Warhol for this reason (compare Sotheby's London Warhol print results with Christie's London print results - it makes for very interesting reading)

Forum sold one for $66,000 in September!

yep crazy, 

I know the premise of low estimates create interest and involvement. What happens with high estimates? Does that detract from people being involved? I just cant wrap my head around that orange Choose Your Weapon estimate. If it comes in much lower or doesnt reach a reserve, does this blow up in their face as supposed banksy experts?
