Aha, I see that you found them among your motherʻs things, and you have an idea where they came from. And that information is recorded on WikiTree!
If you are asking, really, what to do with them....find out if there is a historical society on Catalina. Or even Los Angeles County might want to archive them. Or New Jersey.
I worry about eBay........I would not want to think of them becoming a collage. But eBay might be the place you could make contact with the Daly family. Maybe there is a webpage for Daly?
