I took a photography class in college during the early 1970s. The campus bookstore sold an inexpensive black and white film that was popular with photography students, primarily because of its low cost. I don't recall what the brand was, but I do remember that it was manufactured in an "Eastern Block" country. I have a vague recollection that the packaging might have been green.
As I mentioned, I don't remember the brand name, and I am racking my brain to try to remember what it was. Is there anyone else here who was taking photography classes at about that time whose school's bookstore also sold inexpensive film(s) from Eastern Europe, and if so do you remember the brand name(s).
I don't have a good reason for trying to come up with the name, other than the fact that it has been bothering me that I don't remember.
