boxful of old Catholic (?) prayer/memorial cards

This is a Marshall Field & Co. branded cardboard box, stuffed full of what appear to be mostly small printed prayer and/or memorial cards and pamphlets along with neatly clipped newspaper obituaries and things like that. Without looking closely at any, I can see 1940's dates and locations all over the place on some of them, at least. Lots have depictions of Saints. One item seen that doesn't 'seem to go with the rest' (but otherwise fell out) is the folded (empty) 'sample pack' of "PABASYL ENTERIC COATED IVC TABLETS", whatever those are/were.

I have no idea what to do with them, but it just seems wrong somehow to toss the boxful in the recycle bin...??
