One is a vinatge-style Tootsie Roll sign, really neat, but it's metal and has jagged edges

so I either need to find/make a box to fit it or find something to tape along to edges

if it'll fit in a garment box (they're usually like 9x13) get one of those for cheap, they come in like 4 pack and they're fancy. otherwise DIY build your own box with cardboard
