Porcelian Trinket From My Childhood

As a child I remember seeing this porcelain trinket box in my grandmother's house (Her parents came from Poland). I have had this in my possession since her death in 1976. She married my grandfather who fought for the Germans in WWI and was sent to prison camp in America.
He died before I was born but I have been fascinated with their background which is why I still proudly display this piece, even though I don't know anything about it! There are no markings on the bottom but it looks just like two other pieces in the collection which have markings on their bottoms. 2"x 3" x 1 1/2"
