Matryoshka dolls appear as a man or woman with a rounded shape, and painted-on features and clothes. A number of smaller dolls are made to fit one inside of the other and are able to be pulled about near the midsection.
Matryoshka dolls have been around since 1890, when the first was made in Moscow. Not long after, these dolls were made elsewhere, namely in Japan.
The dolls got their name because it was similar to popular Russian female names, as well as the Russian word for mother.
Originally, the matryoshka was made to symbolize motherhood, namely the mothers of large families who are well fed, leading to the portly figure of the doll and her "family" inside of her.
There are a variety of matryoshka styles, though their differences are subtle. Sergiev Posad is the classic style of these dolls, named from the area they were made, and others include Polkholvsky Maidan and Semionovo dolls.
