Warren, Connecticut. I was going through some boxes of saved stuff (I have many, too many) and found a piece of The Berlin Wall that my friend David Darling brought back from Berlin for me in 1989 when it came down. If you don’t know much about The Wall you might explore the Wikipedia entry or, better yet, check out the movie: The Lives of Others.
Small objects like this (1" across) can be wormholes back through time to eras we know little about. The internet being what it is these days, all you need is a fragment like this and you can put together quite a story about a time and place that doesn’t exist anymore.
