I saw this idea and thought it was cool, especially since we've lived in a few places around the country. My husband was cleaning some of his drawers out in the bedroom and tossed an old map book so I thought it was perfect time to do this project which only cost me about 8 bucks in frames.
I decided on doing 5x7's and went to good ol' WalMart and purchased cheapy frames that were less than 2 bucks a piece. Got home, traced my map locales to fit the frames, cut and framed. Then I noticed I bought frames without the hangy things. (that's what I get for being cheap). So I had to improvise and hooked some twine to them to hang.
I like the way they turned out. I'm not very good at hanging pictures straight so I went for a mix-up look so hopefully you can't tell they are crooked. They look straight to me, but that's my problem I always have with hanging stuff. It always looks straight to me, not to others lol.
