Digital BW, The Print

Hi Clayton-

Any chance those print stacks were put into the room (whenever that 
was), shortly after it was painted, stained etc?

Long ago and far away, when I was doing research on silver-based prints, 
I found that oil-based paints, varnishes, etc. can outgas for as long as 
a year.  Latex/acrylics do so for about 30 days.
