Antique Oil Lamp & German Porcelain Figurines

This is a really nice little American made antique tank type oil lamp with a picture of a man and woman and they look like they are digging up potatoes or something in a basket. I don't remember the name of this lamp but will update if I find it. The porcelain figurines are of a boy and girl and they are written in German, the girl says, Good Night and boy says, Good Morning at the bottom of each of them. I remember my German grandmother saying that in German so they are special to me.
