Photographs
originally submitted by Joe Stecher:
Any photograph from a photography studio. I have pictures from my parents graduation in the 1960's, but I cannot legally make copies of them because the photography studio (if it even still exists) owns the copyrights on them. If, in the future, these pictures begin to deteriorate, I still cannot make copies of them. If for some reason, they werer destroyed, they would likely be the only copies in existance to have been destroyed.
Stifled uses
Joe Stecher:
Make copies for posterity.
