I wish you luck… I don’t know anyone off hand who has all the issues. And those that do, are probably tattered and torn and fragile. And those that aren’t, I would be hard pressed to think if they had all the issues, and in great condition, that they’d part with it. The Sierra Community is full of “Collectors” of all things Sierra! 🙂 I do know there’s PDFs of almost all the issues, if not all of them, available here. But you probably want the “authentic” thing.
