Antique chalk pictures

Good morning everyone! I have been looking at these pictures for a year now. The store originally they wanted a couple hundred. But she told me $100 for both the other day. So I went and picked them up. There's a paper that goes with them. That tells who each person is. And that this was from 1900. The single picture is a normal size. But the family one is much larger. I've never seen one as big. I have some other old pictures, that I'm not so fond of. So have been looking to buy antique lithographs to put over them in the frame. I'll get better pictures later. The lady in the single print is the same lady standing in the middle of the big picture. Also the frame on the big one is slightly rough condition. Anyone know how to fix up? Or should I leave it? Thanks for looking!
