The simplest thing I can think of is, some Newspapers & large Libraries have microfiche printers... next comes the graphic arts equipment I've worked with .... A Lucy... is a large overhead projector type enlarger that you can blowup just about anything from..... or have them printed from an 8x10 enlarger, or scanned on an 8x10 or drum scanner... or cut up and scanned on a 4x5 film scanner... there is always more than a few ways to do things.... My 1st choice... call your largest library.. 2nd... call KINKOS... I'm sure they have had this thrown at them before... if not.... wake'um UP.... But in general... a good idea worth follow up.
