Framing lithographs

[Dreamcazman]

I'm on the hunt for a suitable frame for my Skyrim lithograph, it's 24x36 so it's not exactly small. I don't want to buy a 'cheap' frame as I want to make sure the lithograph is well protected so I'm looking into custom framing.

Frist off, the picture won't be hanging in direct sunlight so I don't think I need to go to the expense of UV glass, but is normal glass ok, or should I go for perspex (plexi glass)?

Also from what I've read, it's best to have a mat around the edge so the litho doesn't actually come in contact with the glass, but AFAIK that involves sticking it to the backing board, something I don't really want to do if I ever want to remove it.

Anyone knowledgeable in this area?
