As I was shoved into a corner by my fellow Londoners on the tube the other day, I noticed a new poster in the Picaddilly line carriage. The work by artist Nils Norman is an adaptation of the above-ground poster that highlights the tourist attractions at ground level. It emcompases “a series of unrealised and fantastical buildings and systems alongside other artists’ unrealised proposals for London… a vision of London as an ecological haven inhabitated by Utopian and Dystopian machinery…”
Amongst the cornecoplia of buildings that transform overground London are Super Studio’s white-tiled block and Ron Herron’s Walking City:

Anyone know where I can get a copy of the original overground poster that this is based on?
I thought they might flog it at the TFL shop/museum ( http://www.ltmuseum.co.uk/ ), but alas not…
If you’re really desperate, I’d contact TFL themselves at http://www.tfl.gov.uk/help/default.aspx
