They covered most of the colors of 70s and 80s telephones (Trimlines, Princess, 2500 sets, etc.) from Bell as well as some of the later colors offered by AT&T. They were all in thick silver envelopes stamped with expiration dates and warnings about keeping them out of the light. I guess they have the potential to discolor with time (as we know plastic will do) and would then no longer be useful as standards. Maybe not "useful" but a cool piece of history. I guess it could help someone repaint that old HP terminal! -- jht
