on the overground line between new cross and london bridge someone has done a big 'Peggy Mitchell' piece in pink. Next to that someone added a big 'Pat Butcher'. I will try and photo it from the train window some day.
I love the street sign for Varndell Street, just off Hampstead Road near Euston, which someone has helpfully and appropriately altered to 'Vandal Street'. See also: Pilldrop Crescent, formerly Hilldrop Crescent, in Holloway.
I've never been to Manchester but it gladens me to hear that the first letter in the sign for Canal Street gets painted out with predictable regularity.
Wow, are you actually tox? You're a tag legend.
