This summer in Stamford they had statues almost in every corner, something that apparently happens every year for a few months. Not sure what happens with the statues afterwards but am sure they are sold off for a vast amount of money to people who have grown to love them. I would like to have bought several of them. There was a hippo in rusted iron in one corner. A moose made of scrap metal with a lovely soft nose. A snail looking thing made from a giant chain like you have on your bike - it was called 'The missing link' - ah - must have been a link chain?
Such a great idea. Think more cities should get local artists to display their arts in unused street corners. It really cheered me up walking around and suddenly finding a dragon fly on a wall.
