Digital BW, The Print

Paul, FWIW, I have some silver prints on resin-coated paper from the 
early seventies. They were dry-mounted to shirt cardboards(!)with an 
aluminum foil barrier between. The cardboard is yellowed and stained; 
the prints are astonishingly well preserved. No change in 
them whatsoever as far as I can tell.
