This is the sort of thing that makes flea market photo hunting such a delight. Small, crude prints which nevertheless perfectly preserve a moment.
Photographs I've gleaned from flea markets, junk shops and sometimes ebay. The cheaper the better. Anything with a story that can be extracted from hand written notes, location research, local histories, census records......anything. A small band of fellow enthusiasts worldwide have helped me with many of these. Of course there are always mysteries that defy research, but there's even a story inside these. All images can be viewed at super-size on Flickr.
