Thanks everyone :-) Phil,Oldboy, despite the gloomy nature of the place I am sure there was optimism and this does shine through in the graffiti. Some more here which shows the attempt to be upbeat despite the situtation. I think the bright colours speak volumes. This was in another smoking room in the same place.
Bal, I think the smearing is where they've tried to clean the walls up. The nicotine stains were horrible and the smell was worse.
Chris, it is fairly recent since they left - December 6th just gone.
