Ignore me, found the threads elsewhere that I need x x

I'm sure this has been covered a 1000 times on here.

How do people display / store their autographs??? I'm getting a build up of envelopes with signed photos in and could do with a way of storing them, but still accessible to view.
Are there certain folders you can get with a certain type of sleeve to put them in???

Any help would be massively appreciated.
