I was in a little photo shop the other day, and in their dwindling paper section, I saw some yellow boxes of Polycontrast and other goodies. No Polymax, sadly, but a 50 sheets box of 11x14 Panalure. It seems to be from the same era as the Polycontrast, so probably the last batches that Kodak produced, but no trace of an expiration date anywhere. Would that be worth bargaining for, or is it already fogged beyond hope?
