Slightly off-topic, digital that is, but is there any value in old unused film besides nostalgia? I came across some boxes of old ER 135, PX 135, FX 135, EL 135 and HIE 135 while cleaning some dusty corners. They all have expiration dates almost 30 yr ago, i.e 1981 - 1983.
I guess I could always display them in my curio cabinet to show what it was used back in the day.
