I need help with paper selection and how to bind paper...

Hey guys im in the middle of a uni project at the moment, its going to be a infographics poster about Auschwitz.

I have all the information and what graphics to use im just struggling to work out what paper I should use and the poster will eventually fold into a book like a constantine effect.

I need to know for instance If I were to use A3 paper and needed to stick 6 sheets together what is the best way of binding them so it will fold to a book size but also looks clean and like a constantine poster instead of just sticking them together.

With the paper do you guys know of any paper that stands out to you that will give quite an old feel as Auschwitz was based in the 40's ad I want something to represent that.
