i think the address was KODAK Rochester 8 .. or something like that.
it was probably sent back in a wooden box, but to drop it off you had to look like you came out of a manet painting men had to be wearing a bowler hat and women a bustle with a parasol.
from what i remember originally the images were emulsion on paper, and they were floated off onto glass to make the contact prints ( think polaroid emulsion lift )
then george eastman started to commericalize the use of celluloid as a substrait but in the early 1900s the preecher from the mid west who invented roll film sued him for millions (then millions, not now-millions) and won, nearly bankrupting Eastman there was a multi part series that floatedaround a few years ago about the beginnings of KODAK probably made by A+E or the history channel or nova ..
if you can find it its worth the watch...
