Going through stuff at my grandparents house, we found a couple prints that my grandfather had made probably in the late 1920's (never knew he printed, but my grandmother says it's true). Unfortunately they're rolled up, and trying to unroll them breaks the emulsion. I'd like to save them, and my thoughts are to soak them in either photo-flo or a print flattener, then perhaps a bath in Sistan. No idea what kind of paper it is, but it's definitely fiber (reckon there wasn't anything else at the time), and they seem to be fixed properly (unlike some of my early prints, there is no sign of browning). Any thoughts or suggestions from the experts out there?
