Older papers from 60`s &70`s held up better than todays papers in storage. Todays papers have additional emulsion components that allow them to be manufactured and sold immediately without 6 months aging. Good for manufactures, bad for users as the shelf life is shortened considerably.

20 years ago the Ilford rep, when Kodak and Ilford had reps, told me freezing added little to shelf life.

The good news is I believe the papers today have better tonality than they did then, specially the multicontrast. Ilford Gallery is just outstanding.Knock your socks off good.
