bjacques -- True, so let me amend my statement to being jealous of your particular find. :) Though it has been a while since I've seen glass negatives at the flea market.
Once, at a second-hand bookstore I found several pictures that could be dated arounds the 50's all of the same young woman. I don't have them anymore, I mailed them all to a friend of mine, along with a letter where I pretended to be that woman, writting to her fiance who is away at the sea :P
On a very tiny sidenote, somewhat inspired by The Wandering Dogs last comment. Where I grew up, there was a former workhouse, which had been used as a council run OAP home. When the council relocated, my friends and I used to frequent it. One building, was quite low, single story, and had a sizeable doorway into the attic space, wherein we found a letter, still in its envelope, open, dated 1915, from a young man who was at war, lamenting his inability to see the recipient of the letter, his wife. I wanted to take it (mainly as I believed the stamp might be worth something) but we were superstitious youths and left it, lest we invoked the wrath of the either the writer or the addressee.
The young man who wrote the letter never made it home. My friends mother checked the council records, and found the records of both his death, and the addressee about 20 years later. Out of all of the buildings, it was the only one flattened when the site was developed into housing, and I still regret not having taken that note.
