To celebrate the beginning of the works for Tate Modern's new extension, Swedish artist Martin Karlsson has created a project on the 100-metre hoarding that encloses the building site.
'London - An Imagery' (2008-9) takes as its starting point Gustave Doré's gothic etchings published in 1872. In this film Karlsson tells us how his drawings update this portrait of the city and its inhabitants. The project could be seen on the hoardings behind Tate Modern during 2010.
