Yes, indeed, it is very famous image in Russia. It is included in every fairy tale with Baba Yaga, and sometimes even without her.
For those who can read Russian, or for those, who is enough with Google translating, read this
Wikipedia article.
I also found some other article, in English:
Just as Red Riding Hood has a wolf, Narnia has the White Witch, Harry Potter has Voldemort and everywhere has a bogeyman, fairy tales and children’s stories the world over have a villain, and Russian folktales are no exception. In Russian folklore this lot falls to Baba Yaga, the scary witch who lives in a mysterious dark wood in a house with chicken’s claws at its four corners. Whenever the witch hears someone approaching through the forest, the house can turn to face them and the victim can be lured inside, there to be ground in a pestle and mortar. Shades of Hansel and Gretel, perhaps. And when not in use for such a grisly purpose, the pestle and mortar double as a vehicle for flying through the sky.
