Found Magazine is a great concept of creating a magazine. I ran into this mag on a trip to NYC and loved it right away.

The beauty of their concept is simple and strong. Found Mag collects found stuff everywhere, on the street, at work, in garbage cans, anywhere!
"love letters, birthday cards, kids' homework, to-do lists, ticket stubs, poetry on napkins, doodles-- anything that gives a glimpse into someone else's life."
This collection of items is often hilarious, sometimes heart-breaking, but always fascinating and put together in a magazine.

Founders are Davy and Peter Rothbart
