The XX: Now, this is an auction

While some people will pay a fortune for a vague promise that a celeb will follow them on Twitter, The XX know how to make a charity auction:

The xx are now making the final preparations for their final (read: last chance to see them play for a very long time!!!) tour after which they head home for some well-deserved r&r before starting work on the follow up to xx. The band have decided rather than let the lightboxes sit in storage they will put them to good use by auctioning them off with all proceeds going to one of the band’s favorite charities Amnesty International.

They come as a set and sellers won't split, which has apparently put Exene Cervenka off bidding.
