gregor graf
at first glance gregor graf's 'hidden town' photos seem a little unreal, then you notice that all he's done to them is to retouch out the signs. interesting how such a small gesture can obliterate any feeling of a place's specificity. you can see more of gregor's work here. thanks to hans for the link.
