If you want your autographed poster to look pristine even after a decade or two (or more!), then don It fold them. You're thinking that a good way to store it is to fold it up and put it inside a cabinet, aren't you? Well, it's not! While it may not rip or fade away inside a file cabinet, you will be left with many creases that are hard to take out. Even if you iron the poster, it still won't look as good as when you first got it. So please, don't fold your poster if it's not necessary.

LETTING IT STAY OUT IN THE OPEN
Getting blown away, getting wet, someone accidentally stepping on it—these are just some of what may happen to your autographed poster if you just let it out in the open. Sure, on its own, the poster might seem fine now. But you never know what outside forces could do to it. Wind can easily pick it up, blow it to the street, and a passing car will rip it to shreds. And that's just one scenario. By just leaving it out there, your poster can also be exposed to fire, rain, animals with sharp claws, and more. Treat your signed memorabilia with utmost care if you want to preserve it!
