A while ago I went through a phase of checking Found Magazine's Find of the Day - if you've never visited the site, they ask people to send in items they've found; anything from photos, notes and letters to ticket stubs, to-do lists and so on. It made me constantly on the lookout for similar items on the street, but I never found anything of interest.
One winter, when I was a kid my brother and I were taking our sledge to the park and found a cassette tape in the snow. We pocketed it excitedly, wondering what could be on there (a mixtape for a loved one? Secret spy messages we were never meant to hear?) but by the time we got home we realised it had fallen out of his pocket.. devastating!
Last week I bought a book from Oxfam and found this photograph inside. A picture of a happy family, seemingly used as a bookmark, that the owner will never get back. Have you ever found anything interesting? (Oh - I also bought a camera from a charity shop that had a half used roll of film inside, which was pretty exciting to develop!)
