At first, the Danbury estate sale didn't seem promising. But in an upstairs room filled with boxes, that's where Urban Archeologist Greg Van Antwerp found one of his most treasured finds.
"In a cardboard box, wrapped in a sock was a piece of black glass," he writes in his most recent blog post. "The edges were sharp and I wasn’t sure it was anything until it caught the light. Though dim, I could make out a couple standing beside a clapboard home; it looked and felt very old."
He wondered whether he could develop a negative that may be more than 130 years old.
And if you're part of a local historical society, Van Antwerp has a message for you:
"Knowing now that I can develop these glass negatives has led me to offer outright to any local historical society — if you have some glass negatives that you would like to see developed; I will volunteer my new skill for free. I may ask only to keep a copy of the developed image."
