From the British Library:-
http://www.bl.uk/reshelp/atyourdesk/newscopy/permiss/newscopyright.html"For an unsigned or anonymous article: copyright expires 70 years from the end of the calendar year in which the work was made, or made available to the public. For example, a newspaper published in 1930 is out of copyright in 2001."
It's also technically possible, but the results vary, when you scan a newspaper article it may come out looking like lots of little dots (search halftone images on google to see what I mean) as this was the process used in newspapers of the time, although things are improved nowadays (but then you get into the copyrighted scenario), hope this helps a little.
