I have an unopened 100 sheet box of 8 X 10 paper which I have had refrigerated, however can't say for sure how it was handled pryor to my acquisition. I will never use it and would like to trade it for something I could use. Have an interest in one of those little self timer gizmos that screw into a cable release socket however an open to anything else. Maybe a Brownie Hawkeye camera. I use, Olympus OM 35mm, Richoflex TLR, Hasselblad, various toy cameras, several 4X5 and 8X10 cameras. Bill Barber
