So far the biggest graffiti wall in China , done in 2003, in ChengDu, by MiG and FBL crews from GuangZHou Canton. It is about 2m x 32m. They've been painting since 2000. Thanks to Sic for the image (484k) (If you can't see the image in your browser, right-click the link and download the image first. It's very wide.)
