I found a roll of ORWO NP27 that had been exposed and then taped up in a box that the movers packed in 1982 and has been stored in my garage ever since, 4 years in CT and the remainder in TX. I'm surprised there is an image at all. I kinda like it, but the ageing process is a killer!
ORWO was eastern European film that was available from some of the NY photo stores and used by poor graduate students (like me!). It came in several speeds... DIN 18, 22 and 27, if I remember. I can probably still find a few unexposed rolls laying around my study...
