Babushka=Matryoshka

A matryoshka doll (Russian: матрёшка, IPA [mʌˈtrʲoʂkə]) or a Russian nested doll (also called stacking dolls or Babushka dolls) is a set of dolls of decreasing sizes placed one inside another. The plural form matryoshki is used when referring to more than one doll.
A set of matryoshki consists of a wooden figure which can be pulled apart to reveal another figure of the same sort inside. It has in turn another figure inside, and so on. The number of nested figures is usually six or more. The shape is mostly cylindrical, rounded at the top for the head and tapered towards the bottom, but little else; the dolls have no hands (except those that are painted). The artistry is in the painting of each doll, which can be extremely elaborate.
Matryoshki are often designed to follow a particular theme, for instance peasant girls in traditional dress, but the theme can be almost anything, ranging from fairy tale characters to Soviet leaders.

HISTORY
Matryoshki are a relatively new Russian handicraft; the first one dates from 1890, and is said to have been inspired by souvenir dolls from Japan. However, the concept of nested objects was familiar in Russia, having been applied to carved wooden apples and Easter eggs; the first Fabergé egg, in 1885, had a nesting of egg, yolk, hen, and crown.
The story goes that Sergei Maliutin, a painter from a folk crafts workshop in the Abramtsevo estate of a famous Russian industrialist and patron of arts Savva Mamontov, saw a set of Japanese wooden dolls representing Shichi-fuku-jin, the Seven Gods of Fortune. The largest doll was that of Fukurokuju, a happy bald god with an unusually tall chin. It nested the six remaining deities. Inspired, Maliutin drew a sketch of a Russian version of the toy. It was carved by Vasiliy Zvezdochkin in a toy workshop in Sergiyev Posad and painted by Sergei Maliutin. It consisted of eight dolls; the outermost was a girl in an apron, then the dolls alternated between boy and girl, with the innermost – a baby.
In 1900, M.A. Mamontova, the wife of Savva Mamontov, presented the dolls at the World Exhibition in Paris and the toy earned a bronze medal. Soon, many other places in Russia started making matryoshki of various styles.
