SPOILER: It's highly unlikely that there would have been enough resolution in the original print to see a headline, let alone read the date on the newspaper. If there were, they would have been able to easily see the date with a simple magnifying glass. Only photographic enlargement performed on the original negative could possibly reveal additional small details. Instead they created a new negative from the print in order to make the enlargements. Since the new negative is made from the print, there is no way to recreate details that can't be seen on that print in the first place. If your original is missing enough legibility to see the fine details, no amount of copying or enlarging can possibly improve upon that. Also, there's no need to read the date - in the first enlargement, probably, and definitely in the slightly larger second enlargement, it should be possible to identify the date from the layout of the newspaper page.

Opening credits are printed on the pages of a book; it is also stated that this is a true story.
