Ken's got himself a new piece of art - entirely drawn by Londoners. The People's Panorama, conceived by artist Ben Johnson, is a hand-drawn view of London that's just gone on show at City Hall:
The artist...based the work on a photograph he took from the top of Canary Wharf. He divided the image into 1280 squares measuring three inches each. Members of the public were then invited to contribute a pencil drawing on an A4 paper based on a specific section of the picture.
Contributors include Peter Blake, Norman Foster and Ken Livingstone himself. It's on free display until 10 April, when it leaves for a tour of hospitals. We suggest they also submit it to the handmade cartography pool on Flickr.
