Yes, it is surprising how well all those postcards arrive, no matter if they are on regular RC paper, on Ilford postcard paper (which is I think Ilford Gallery paper which has a bit thinker paper base), FB, cyanotypes, Polaroids, even the very small Fuji Instax postcards arrived well. And - it is a postcard exchange, so a bit of wear should be part of the fun
Has anyone sent Fuji Pack film prints out before? Would they survive I wonder? Hmm, ideas, ideas... I have a whole bunch of FP-100B that expires in November 2011, very interesting... too many ellipses...
