Transport for London has a history of filling what would otherwise be commercial advertising space with some artwork posters, for the edification or social engineering and control of its captive audience of travellers.
This one by Anna Barribal is either ironic or sinister, given the mass surveillance systems and the crowds of people, to which the viewers of these posters will be exposed to on Transport for London's Underground railway Tube or bus networks.
This is one of a series of posters entitled 60 miles of beautiful views
We will see if we can get a photo of one of these posters in situ, without getting harassed or illegally stopped and searched or falsely arrested by jobsworths.
UPDATE: here are a couple of photos of this poster taken at Embankment Tube station, southbound on the Northern line taken on 2nd July 2008.
