( Typical Russian doll called "Matryoshka", made of painted wood, it opens and inside there is a smaller one, it continues opening until it reaches the last one and there is a tiny one. There are usually five. If the egg is larger, it may have more dolls.)
My grand mother was from St. Petersburg, Russian Empire, from 1712 to 1918 (being replaced by Moscow for a short period between 1728. My mother was Russian, and I am half a russian and half italian where I have born in Roma.
