This is a cloche. Cloche means bell in French. I believe a cloche was originally referred to as a small glass dome used to force plants to bloom (like a mini green house). But in decor terms, it's usually a display (raised on a stand) under glass.
Idea for old book pages. possibility for that giant vintage cloche I don't know what to do with. where to display though. hmmm maybe instead of picking one inspirational quote, print all my faves and keep them in cloche and on display! a solution!
