folded cases/sleeves for each set of poster and flipbook. 

I changed the idea of having the poster as a sleeve on the flipbooks because I didn’t want to have a crease down the middle of my posters to allow space for the spines of the books. Also, having them as sets in cases/sleeves help reinforce that papers are less commonly used, probably hidden away in boxes or library collection. Vintage maps are now more of collectors’ pieces, hidden away in attics etc.
