Well, I just keep them in some storage. Never threw even one issue since more than a decade.
I intend to make a library of some sort, where I can put it on display. It would be like a time capsule, and a great read through back from when technology was still naive to a time where we have reached quantum computing!
As for some poster, I use it on walls. Although I want to convert into some framed posters to make it more appealing.
