Diana Hale found a bunch of postcards and used them to invent the Philpott Lake Project http://philpottlakeproject.tumblr.com
The way that worked was that she sent all the people who agreed to alter postcards each a postcard. Mine arrived just before I went to Maine and I lost it… I had taken a photo of it so I used the photo to make a print and began from that. I was thinking about a lake that spawned life, somewhere off the map.
Diana sent me back the above card. It was folded and closed with two stickers. I presume there was nothing more inside. Nothing beats Matisse!
