Banksy artwork tops £200k on eBay
Portobello Road wall attracts hot bidding
The owner of the wall in question is Luti Fagbenle, and he's quite sensibly protected the piece with "per-specs [sic] glass".
The successful bidder will, in addition to the sale price, have to stump for the "removal and replacement of the wall". Fagbenle notes: "I advise you seek your own costing for this but shouldn't cost more than £5,000." ®
