This just in from Jeff Glickman (you'll recall that I sent him the print we got from the Miami Herald many years ago):
" I have received the photo. First, some good news: This photo appears to be a print from a negative, possibly a first generation print from an original negative, although this is yet to be conclusively determined. The print does not suffer from a loss of information due to half-toning, nor does it have any digital compression artifacts. However, given the time period for the photographic chemistry, the grain size is large relative to the rivets, which are the objects of interest. I will be working over the next several days to determine what specific structures within the window patch can be discerned."
