Giovani unmarked lithograph?

got the bottom picture of Mary and Joseph off a guy's garbage pile found the top photo of the 12 disciples remembrance of First Holy Communion underneath the picture dated 1914 I don't know much but I think the picture of Mary and Joseph is a lithograph that is unmarked and I'm thinking it's pretty old but how do I tell when I use a magnifying glass to see a lot of dots and no they're not all in order and its color over color I've tried looking up the remembrance of First Holy Communion it's from Germany and I believe it has gold paint as border. the picture of Mary and Joseph and baby Jesus is very colorful deep rich color any information would be great
