Hello, Ben here.
This has been on the wall in the stair well between floors two and three for a few years. Created before my time by Ben Everitt. It's a world map made from stamps from the relevant countires.
It's a wonderful thing. Smart, witty, beautiful. I stuck a few pictures of it on my Flickr a few weeks ago and it's had hundreds of hits and favourites, so I thought I'd share it here.
Actully writing this now makes me think we should probably make prints of it. Subject to legal permissions etc. Who'd be interested in that?
