Oooh, they're nice Quincy, especially the first two. It makes me so angry when these yobs spoil it for eveyone, especially, as you say, the kids. They are also taking money from charity.
I hope to get out and about, outside the city centre, for a day or two and get some of the rarer ones. But don't think I'll have time to get them all so will have to cheat at St George's Hall!
When I photographed Art Vandelist in East Village, it was sort of brown and white wallpaper, some of it peeling. Now it's a green one, with Mr Men and other colourful characters on it. I can't keep up!
Good luck with the rest of your search!
