I have a box of Panatomic-X in 3-1/4 x 4-1/4 sheets marked "Develop before Sept. 1960".
Wow. That's some procrastination! I don't think that I can match that.
Unopened box of 2 1/4 x 3 1/4 Ansco color- Develop before Apr 1950
sorry for going off topic

So if Efke's goes what would you replace it with in sheet format? I am not sure i know the answer to that from what I tend to like... Maybe fp4+???
FOMA/Arista 100, In sheet form I always rate it at 50 and like the look it gives
