Vassilia and the russian dolls

Vassilia has no father nor mother. She lives in poverty, working hard without losing her kindness. One day, to thank for helping her, an old hunchback gives her a piece of wood and says these words: "Knock three times on the small wood and Mamouschka will appear ..." With Mamouschka, the magical doll, the life of Vassilia will never be the same, especially since a Russian doll often hides another ... and another ... and another!
